MTG Salvation

This seems really hard to abuse. Most of the time, it will be worse than Warden of Geometries.

It certainly has some explosive potential, but it seems relatively narrow. If I'm dedicating 4cc cards to a ramp strategy, the ramp effect needs to be pretty reliable for it to make the cut, and I think this may simply tap for C too often.

Might have been interesting with a bigger body but it feel like most of the time it will tap for 1 or 2 then eat some removal or block something.

Maybe if you gained the mana when you drew or it was coloured mana, but maybe those would be too good because it would make cantrips free.

In cube I can imagine big plays of Sylvan Library, Brainstorm or Ancestral Recall. Too rare and unreliable to pull off methinks.

Finally, a reason to play Ancestral Recall

I think this is playable in a cube that supports storm and nowhere else. Any draw 7 effect makes this absurd (even without colored mana), but because it's so fragile and weak in a vacuum you really need to be powering out combo kills with her.

Slam dunk for commander cube, thought probably a lot harder to slot in conventional environments.

For a second I didn't see that tap symbol and got really excited thinking I got an increasing amount of mana free for each draw. This card however is meh, unless you are in commander cube.
