Max Thompson Jr, The Hillbilly

Tinkerer — Once per turn, you may cast an
artifact spell from your graveyard. Spells cast
this way enter the battlefield with a tinkerer
counter. If a permanent you control with a
tinkerer counter on it leaves the battlefield, exile
it instead. (tinkerer counters can only be placed on artifacts and can't be manipulated.)
Chainsaw — {x}(max 5): The Hillbilly gets
+X/+0 and trample until end of turn. Activate
as a sorcery and only once per turn
