Dowsing Dagger (2)
Artifact - Equipment
When Dowsing Dagger enters the battlefield, target opponent creates two 0/2 green Plant creature tokens with defender.
Equipped creature gets +2/+1.
Whenever equipped creature deals combat damage to a player, you may transform Dowsing Dagger.
(T): Add 3 mana of any one color to your mana pool.
I know this requires a lot of hoops to jump, but it turns into a non-legendary, repeatable Black Lotus (Lotus Vale). For 4 mana when it drops (with a flier out), it can flip and then be used the same turn, so it costs a grand total of 1 colorless for an extra 2 damage to the face and a Lotus Vale.
Is there a way to break this card fast enough? As is, I can't think of a way to make this easy, Auriok Windwalker is the only creature with flying that has "equipment" text, and it taps to equip which misses the point. Clearly this doesn't really fit into many decks unless there's a stoneforge build that makes ample use of fliers.
Also Stony Silence/Null Rod kills it, Wasteland kills it, etc.
Any other ideas? Seems like a fun card to brew with, possibly.
