Jon led off the duel by playing [1], and had nothing further for his turn. Kai responded by playing [2] on his turn and passed.

In his second turn, Jon played [3] and tapped out to cast [4]. Jon tried to end his turn but Kai cast [5] in his end step. Jon discarded [6], the best fatty ever printed, with just a hint of a smile. On his turn, Kai responded by playing [7] and tapping out to produce two mana to cast [8]. Having nothing further, he let Jon go again.

Jon began by attacking with [4], which [8] could not block because of [4]'s protection ability. Jon then put [9] into play. He tapped [1] to activate [9] and tapped [3] to cast [10] with three +1/+1 counters. Contemplating using [11] during his attack, Kai played [12]. Then he attacked with [8]. Jon sensed a trick and let it through. Indeed, [11] would have let Kai kill [10] and get damage through anyway. Kai then tapped out, taking a point of damage, and since he had done damage this turn he was able to cast [13] without having to sacrifice it. Then he let Jon go.

Jon attacked with both his creatures, and Kai still couldn't profitably block. Jon cast [14] face down and put [15] into play tapped. On Kai's fourth turn, he just cast the [16] he just drew and held back his creatures.

Jon untapped, drew his card and thought for a bit, eventually deciding to attack with [4] and [10]. Kai was ready, quickly blocking [10] with [8] and [4] with [13]. [4] got +1/+1 when blocked, but that was not going to be nearly enough. Kai tapped [12] (taking another point) and [7] to cast the [11] he'd represented targeting [8]. Now [8] was easily big enough to kill [10] and survive. Then, he tapped [2] and [16] and sacced [7] to cast [17] targeting Jon. It resolved and [13] got five +1/+1 counters. Jon could only let both his creatures die while Kai's lived. After combat though, he cast [18] at [13] to finish it off (tapping [1] and [3]). Kai let out a sigh but even if he had held [11] back to protect [13], [18] would still have done just enough damage. [19] came into play tapped, and it was Kai's turn. Kai played [20] and cast [21] (tapping all his lands, taking another point) to destroy [1], hoping that shutting down [3]'s ability to produce colored mana, especially reusable red mana, would cause Jon problems . [1] also happened to be the only target in either deck that would let Kai gain a life upon resolution of that spell. [8] attacked for the second time and then Kai passed the turn.

Seeing no blockers, Jon attacked with [14]. Kai tapped [16] and cast [22] destroying it. If Jon had had a white source other than [15] he would have been able to flip [14] over and save it. Kai was relieved to have dealt with the potential flyer before it started causing trouble. Jon decided to just play [23] tapped and be done. On Kai's turn he just attacked for two with [8] again and was done.

Jon drew for his turn. Looking to shake things up, he cast the [24] he topdecked by saccing [15] and using one of the mana to activate [9]. Jon discarded [25], and frowned when he saw Kai discard [26]. Both players drew up to seven and Kai tapped [2], [16], and [20] to cast [26]. Jon played [27] and passed the turn. Kai attacked with both his creatures. Jon tapped [19], [3], and [27] (taking a point) to cast [28] targeting [26]. It resolved, killing [26] and letting Jon draw a card. [8] got through unmolested though. After combat, Kai played [29] and tapped [2] and [12](taking a point) to cast [30].

On Jon's next turn, he put [31] into play tapped. He quickly counted the cards in his graveyard and then he tapped [19] to activate [9], and tapped [3] and [23] to cast [32] threatening to kill all of Kai's creatures. Kai also looked over his graveyard, and then he tapped [29] and [16] to cast [33] targeting [8] removing [13] and [26] from the game. In response to his own spell, he activated [20] targeting [30]. When the dust settled [33] destroyed [8] (which was destined to die anyway), but [32] was now a point shy of sending [30] to the graveyard. Kai sent [30] to attack unhindered next turn. Then he played [34] and tapped it, [12] (for colorless), [16], and [20] to cast [35] at Jon. It would have been just enough damage to kill him, but Jon was able to cast [36] pitching [37] to counter it, taking a point but staying alive.

Jon untapped and tapped [23] to activate [9]. He used one of the mana to cast [38] targeting himself to draw three cards. Jon was now able to remove the immediate threat. Using the other mana in his pool Jon sacced [27] targeting [30]. Then he cast [39] at [30] by tapping [31] and [3]. He even gained 2 life in the process. Jon then played [40] tapped and was done. Kai played [41] and tapped it to cast [42], and tapped [2], [12] (hurting himself yet again), [16], and [29] to cast [43]. If either got through unblocked it would be just enough to finish Jon with the help of [29]. To further cut Jon's options, Kai sacced [34] to destroy [23], eliminating a blocker that could have gotten in the way of [42] even if it used its evasion ability.

But Jon still had answers. He untapped and played [44]. He then tapped [40] (removing a counter) and activated [9] to cast [45] (leaving one mana floating), and then tapped [3], [19], and [31] to cast [46]. Immediately upon [46]'s resolution, 420.5e triggered sending [46] and [43] to the graveyard. On Kai's next turn he went for the win again. He tapped [2] to use [42]'s ability, leaving [45] unable to block it. Once that resolved, [42] attacked, and Kai tried to activate [20] targeting [42] after blockers. After that, Kai had been planning to tap [2] and [12] to use [29] also targeting [42]. In response to the activation of [20], Jon tapped [44] to cast [47] targeting [42] though. Thus, [42] was destroyed before the resolution of [20]'s ability made [47]'s drawback lethal. All Kai could do instead was tap [12] (another point) to cast a wall, [48], which was looking rather useless.

And on the next turn, Jon finally peeled the [49] off the top of his deck that he'd been waiting for. He tapped [40], causing him to sacrifice it, and activated [9] to cast [49] enchanting the long-forgotten [6], bringing it into play. He played [50], a dual land, and tapped it and used the other mana that was floating in his pool to cast [51] to return [37] to his hand. [45] then attacked and got through since it had protection from [48]'s color. The game slipping from his hands, Kai tried to cast [52] tapping [2] and [29]. If it resolved it would have done 10 damage to Jon and 8 to Kai. Jon was not about to take the draw though. Instead, he tapped [19], sacrificing it, and tapped [31] and [3] to cast [37], which countered [52]. That was all Kai could do, and the end was near.

On his turn, Jon tapped four lands ([3] activating [9], [50], and [31]) to cast [53] enchanting [2]. He then attacked with all five of his creatures. Even blocking optimally, Kai took just enough damage to die.
