Component Pouch

Artifact
, Remove a component counter from Component Pouch: Add two mana of different colors.
: Roll a d20.
1-9: Put a component counter on Component Pouch.
10-20: Put two component counters on Component Pouch.

45% Chance of 1 counter, 55% chance of 2 counters. Essentially ETBs tapped, but next turn always taps for 2 colored mana of your choice, and can always bank more counters on off turns or off untaps with Ral Zarek/Tezzeret the Seeker/Kiora's Follower. Compares pretty favorably to Worn Powerstone imo, and our playgroup is already excited for the swap. We were also really hoping for a good dice-rolling card, and this fits that bill too. Any other thoughts on this card?

This looks a lot worse than Worn Powerstone to me, since I can only reliably use it half as often. Am I missing something?

This makes colored mana, so you can actually play it in midrange and control decks as a worse Coalition Relic, unlike Powerstone. In ramp you still aren't usually using all your mana every turn, so I think you'll have plenty of time to charge up your Pouch, and you still get the benefit from the fixing that Powerstone can't provide. Not a lock for a swap, but can't wait to at least try rolling some dice.

This just feels like a Worn Powerstone with extra steps.

But in all seriousness, 3 mana to add 2 mana isn't that bad of a deal - but this charging really puts me off.

This seems Worse than worm, but this is better than Hedron Archive IMO. Maybe it's worth test this in my 720 unpoweered cube

Seems pretty solid to me.
Making colored mana is a big deal over powerstone. Probably doesn't fully make up for it being usable inconsistently, but it's close depending on the cube.
