MTG Salvation

Feels like a missed design opportunity. Imagine if instead the "unless" clause said "unless you control at least one other Gate."

That would make it nearly unplayable unless you had an absurd amount of gates

This is the common fixing we've been waiting for!

Yep! It's another Transguild Promenade (itself a decent card) and as a bonus it can be fetched by stuff like District Guide. Three-color decks won't feel so greedy in Limited with this around.
