These are the cards Ive sideboarded: Chalice of the Void: Essential against decks that rely on cheap spells, like Burn, and useful when facing Cascade decks like Living End or Crashing Footfalls
TAUC DIRTY TO ME If youre building around these tap-an-untapped-creature mechanics in Standard, then that might already be as far as you need to go
I really don't have time for a bunch of reanimation because my deck is full of creatures with attack triggers, equipment, answers like Vindicates, ways of saving my team like Teferi's Protection, card flow like Ancient Craving, mana rocks, and ways of getting extra attacks
The decks all about ramping and slamming battlecruisers, and the curve is ridiculously high (The Ur-Dragon isnt here to make those dragons cheaper, either!)
