polymerization yugioh card RA03-EN051 Alt Art (Elemental HERO Artwork) : Quarter Century Secret Rare 1st Edition when the monster is Fusion Summoned. YuGiOh » Polymerization [Alt Art]

Lotus Cobra and Tireless Provisioner produce additional mana when lands enter the battlefield

Quantum Riddler is a space Sphinx that can draw you cards, and potentially draw you a lot of cards if you're playing them quickly

Im down enough on U/R at the moment that Im tempted to put this lower on the list, but theres no single other card Im so confident in that I can comfortably put it above an excellent dual land

While flavor is very important (especially for a top-down set such as this), good gameplay is even more important

One mana for 2 damage just tends to be a great deal, even allowing you to trade up for lots of 3 and 4 mana cards
