Black is amazing at killing creatures and has probably the best removal for that card type in the game
Return that creature to its owners hand at the beginning of the next end step. Being able to pluck the best thing out of an opponents hand and then throw it back at them is a joy, and we thoroughly recommend everyone try it at least once
Then, for WURBG, you can untap all attacking Creatures
I kind of wanted the card to be a dragon, so I said to my team, 'Here's what I want: I want a dragon doing a job you'd never think a dragon would do
Dual-Ink cards may feel clunky or underwhelming at first, but as more cards come out and more players can use them, much of this will likely fall to the side
You want creatures with mana value 6 or greater, preferably sea monsters, to turn Runo into Krothuss, Lord of the Deep and start creating copies of those monsters
