Dion, Bahamut's Dominant // Bahamut, Warden of Light) Dion enters the battlefield with a 2/2 White Knight buddy in tow, then lifts your whole Knight army into the sky with Dragonfire Dive - his static effect that gives all your Knights flying during your turn
I tend to only play him for his ramping effect when I have a decent number of other blue creatures to tap as well which is not all that often in heavy artifact decks
Trust me when I say there are few things more satisfying than rebuying a creature with a powerful ability doubly so when you get an extra card for your efforts
These are the gold cards that Im most interested in first-picking: I consider Spell Queller to be a pretty weak card for most Cubes, but then again most Cubes have Lightning Bolt
Toss in sacrifice fodder like Ophiomancer or Bloodghast and your board grows while your opponents struggle to keep up
If I forget thee, O Adun, let my right hand forget it's cunning
