Isabelle, Commanding Mayor

When Isabelle attacks, you may gain control of
target equipment until Isabelle leaves the battlefield. Attach it to Isabelle.
When Isabelle deals combat damage to a player,
if it has three or more equipment cards attached
to it, you may choose a creature that player
controls and flip a coin. If you win the flip, you
gain control of the creature until Isabelle leaves
the battlefield. If you lose the flip, a random
opponent gains control of that creature until
Isabelle leaves the battlefield.
