Were going to look at each of the new planes and give them a rating based on the very scientific process of what I think. All right, fine, there are some actual criteria Im looking at
Fizzling Collected Company is also a huge swing, while other weird targets include Aether Vial (although be warned that your opponent can choose to not put the creature into play after they see you sacrifice Mistcaller), Dredge, Hollow One (where you get Bloodghast and Flamewake Phoenix), and strange blink decks involving Flickerwisp and Restoration Angel
If a creature with double team attacks, youll conjure a copy of the creature into your hand without the double team mechanic (so that it wont snowball)
This is limited by the cards that work in this ramp payoff + sacrifice artifact space, but there are definitely some like Bristlebud Farmer, Goldvein Hydra, Ancient Adamantoise, and Im sure others
Then the three-drop enchantment makes a 1/1 Soldier with haste on arrival and then when you target just one of your dorks you can make another token and copy this and target the new token
