Thopter Assembly

Holy damn, this thing packs a ridiculous amount of potential, just let it sit in your hand until you run out of tokens and drop it to replenish 5 more. It's splash-able in any deck that doesn't typically run Thopters.

Easy turn 5 win (turn 4 with excellent draw) with many different combinations (mox opal, coalition relic, sphere of the sun, everflowing chalice, etherium sculpter, any myr that taps for 1 or palladium myr, etc, etc) Targetable for an entire turn sets this back but if you can protect it for one turn you win with time sieve. Pentavus lets you get 5 sackable right away but costs alot more (7 cast + 5 to sack). 3 Stars since you need to protect for 1 turn and not drawing time sieve leaves you pretty wide open.
