This sorcery lets you make a token of a target creature you control, with the copy being nonlegendary and gaining flying
Vampires: Vampires also has a ton of upgrade possibilities, with plenty of tribal support from older sets
The Triomes impact goes even deeper, since the fifth color can also be free if you just a sprinkle of it
Sacrifice and Culling the Weak Sacrifice reminds me a lot of Energy Tap in blue, except you have to give up the creature youre using for mana acceleration
This means that cards like Rampant Growth are not included as a tutor, even though they technically could be considered one
You now have three colourless mana floating, and can do it again: tap Basalt Monolith to make three more colourless mana, pay three to untap it, copy the ability using two colourless and Rings of Brighthearth, untap Basalt Monolith once, tap it to make three more colourless, and then untap it with the copied ability
