mtg cards with cipher commander (cause cipher is underrated) : r/custommagic Soulcipher Board // Cipherbound Spirit

I fully expect this to see play over a lot of the more common counterspells, at all power levels

Cait, Cage Brawler A mostly indestructible commander that grows provides lots of interesting Voltron potential

Ley Druid + Juniper Order Druid + Blossom Dryad The trifecta of Ley Druid, Juniper Order Druid, and Blossom Dryad are effectively the same card: a begrudgingly playable ramp spell

It costs a bit of mana, but it works really nicely in decks that want to go wide

Any cards in hand at all, and quickly the card becomes very unattractive for high-level Constructed

Even for cards like Dragons Approach, where you can have unlimited copies in a deck, you can have up to four copies but it then becomes an infinite card
