A top pick for our Ape Tribal
The Aether Heart is a one-shot effect, but that effect is what might be the 7 most powerful worlds in Magic, Take an extra turn after this one. And just like the Marvel, it can sit around on the board for a while while generating energy, making using that effect far easier
When the triggered ability resolves, first the player whose turn it is (if it isn't your turn) chooses which creature they will sacrifice, then each other player in turn order does the same, then all chosen creatures are sacrificed at the same time
This grants Tree of Perdition's ability to another creature, such as Bloodtithe Harvester, which can then tap to set your opponent's life total to 2
And if you just want to play normal match types like Standard or Alchemy and build a deck with the odd booster you earn along the way, you never have to get out your wallet or feel like you should, anyway
