replace Coalition Relic with Darksteel Ingot

Coalition Relic was really good in my deck yesterday. It made Winter Orb manageable against Dan and prevented Matt from locking me out with Opposition.

Coalition Relic is rather annoying, though. Using the card correctly involves lots of administration. In the opponent's end step one must remember to add a charge counter if possible. Then, one must remember to remove the counter in one's first main phase and must decide which colour of mana to add to one's mana pool. None of this is strategic.

Darksteel Ingot is undoubtedly less powerful, but it's also more elegant and—in my view—more enjoyable to use.
