Vessel of Nascency: if you have scryed before, say, in Modern, then activating this card will be really good
Cards that Take Advantage of Sacrifice To get the most out of the creatures dying on the board, this deck plays creatures like: Tergrid, God of Fright is one of our 99 cards, though she is also one of the most hated Commanders in the community, particularly by casual players
Mainly, 2 mana makes it really cheap to cast and it triggers whenever you attack with a merfolk, which is really easy to enable
Additionally, each deck has a planar die, so you have a fresh one you can use to bop around planes
You also get a nice proliferate loyalty ability to boost multiple planeswalkers at once, and a great final ability to take an extra turn
