Put a +1/+1 counter on Garnet for each lore counter removed this way
I love that Blue gets a bunch more of traditional 'wizardly' things, even if some of the effects aren't necessarily what is the most intuitive for Telekinesis or Teleport
If your mutated creature leaves play and then comes back (say, due to Thassa, Deep-Dwelling), then the cards in the pile come back into play as new, separate creatures
Merfolk It might be cheating a little bit to include three cards, but I do so because I think any one of them individually would probably not be enough to really push Merfolk's power level
That means the characters you play need to stay around, as they cant easily be replaced
For example, you can type something like A mouse that looks like a cat and has rabbit ears, or A fantasy sword with a gold hilt and a glowing blade etc
