Ezuri, Renegade Leader (Budget ~230€ / ~40Tix) (EDH / Commander)

Gameplan:

• Ramp up as quick as possible.
• Once enough Creatures and/or mana:
• Tutor up a Craterhoof Behemoth or buff your army with Ezuri, Renegade Leader into oblivion

Plan B:

• Finish with a Triumph of the Hordes attack (10 poison damage are enough)
• Use one of your infinity combos

Anti-Destruction-Boardwipe:
Heroic Intervention
Ezuri, Renegade Leader -> Regenerate
Minimize the downside: Caller of the Claw

Big Mana Elves:
Elvish Archdruid
Priest of Titania
Marwyn, the Nurturer
Wirewood Channeler
Argothian Elder
Viridian Joiner (not in the deck atm)

Big Combos:
Infinite Mana + Infinite Buff:
[Big Mana Elv] making at least 3 Mana + Umbral Mantle

Infinite Mana (during Combat):
Argothian Elder + Maze of Ith + 1x Forest (254) = Infinite Buffs from Ezuri, Renegade Leader

Small Combos:
Umbral Mantle on any tap ability elv + use tap ability + use Umbral Mantle + attack + use Umbral Mantle again

Considered Card Swaps:
Reclamation Sage instead of Acidic Slime
Upside: Elv + Mana effitient
Downside: No Answer to strong lands like Cabal Coffers / Urborg, Grab von Yawgmoth or Gaea's Cradle (enemie elves!) or Eldrazi Temple

Vanquisher's Banner vs Skullclamp
I feel like Skullclamp only gives you (effectively) carddraw before your elvs are buffed in any way.
Because you can't kill off your ETB elvs for cards once they are beyond 1/1.
Vanquisher's Banner on the other hand helps you immense with the plan to never run out of steam and with only 5 mana it shouldn't be a big problem to cast it.
