Just curious if anyone has tried
Vaultbreaker? It's sort of janky, but I've been testing it as an alternative to
Smuggler's Copter.
Dash makes Vaultbreaker come down with haste and can surprise people taking out Planeswalkers.
Pros:
Red spell, can pitch to Chrome Mox
Can be a threat on it's own (vs equipment/vehicles)
Can be played for 2R mana via Dash and no double-red and has haste
Cycles cards in hand when attacking
Cons:
No Flying
Without Dashing, it's a 4 mana spell that is not really a big body with only 2 toughness.
Doesn't cycle if you're blocking
Dash can be mana intensive
