Ultimately, Ive found steel to be fairly metagame dependent working well as a supporting ink, but tends to fall flat in the starring role
Its got enough keywords that even if some of them arent relevant in a given matchup, its likely that others are
It gives cascade to spells cast from the hand (similar to Yidris, Maelstrom Wielder), but only so long as enough damage has been dealt to opponents this turn
Tidus, Zanarkand Fayth (Thrasios, Triton Hero) You'd be hard-pressed to see Thrasios played anywhere other than low-powered Merfolk Commander decks, but the Final Fantasy X cover art is the big selling point here
Feather, The Redeemed A Master Of Combat Trickery Combat tricks, or instants and sorceries that grant stat and ability boosts to your creatures for a single turn, are a staple element of Magic that rarely make it into Commander decks
The potential meta movers will also be relatively cheap to get ahold of outside of it
