ivankov one piece card game ST13-005 R Parallel Emporio The Best Emporio Ivankov OP05-004 UC Awakening

This unassuming 2-mana instant packs exactly the kind of flexibility any Green deck needs: it destroys an artifact, an enchantment, or exiles a card from a graveyard AND replaces itself with a card draw

If you run mostly artifacts, which is an easy task in Mono-Blue, youll get to effectively draw a lot of cards via the Future Sight effect, too

Doubling Cube $8 Doubling Cube requires the right casual deck to be good, but if youre planning to ramp pretty hard, this is a colorless Cabal Coffers a lot of the time

The older pre-modern one will destroy everything power of four, but my favorite is the aftermath four-cost to destroy all three-power stuff and then five mana once later to bring back all small stuff from your graveyard to the battlefield
