Suggested Build: Jeskai Tokens
Where to Find Cards: Khans of Tarkir block, Core 2020, Innistrad block
How to Win: Kykar is an extreme value engine. Playing with creatures such as Young Pyromancer, Murmuring Mystic, Saheeli, and Talrand can easily turn your empty board state into an army of death and destruction!
For extra value, you can play with cards such as Hissing Iguanar, Impact Tremors, Intangible Virtue, and Raid Bombardment to make combat a real nightmare for your opponents. From there, simply add as many low-cost noncreature spells as you can fit in the deck!
Bonus points if you have one of these laying around…
