The one that did surprise me

Invasion of Shandalar / Leyline Surge Invasion of Shandalars effect is a decent enough recursion spell, but if you manage to transform it (and keep Leyline Surge from being destroyed) you can cheat any one permanent in your hand onto the battlefield per turn, which can be absurdly good

Aspirants Ascent Aspirant's Ascent gives a creature +1/+3, flying, and toxic 1 until end of turn

there are many different directions you can take token decks, and theyre all reasonably viable
