That's why I put the "Tap" in, keeps her from MC'ing too many without an esoteric card combo.
Also, put in that attacking the unit's original side takes a MC counter. It effectively immobilizes the unit, and it reverts faster if you use it offensively.
New card:
Charlie's Archons (No Cost)
When Charlie's Archons come in to play, each player may "bid" an amount of colorless mana not to exceed his current maximum mana pool. The high bidder takes control of the card and must pay his "bid".
Each turn, controlling player must pay 3 colorless mana to retain control of the card. If the card becomes uncontrolled, new bids are taken.
2 R Blu G, Tap: Destroy 3 target creatures that your creatures engaged in combat this turn with toughness < [high enough to kill dwagons]. They can't be regenerated
"Leverage. Synergy. Paradigm.
Luckily for you, they paid a lot."
