Flock of the Feather Walkers (Yellow)

As an additional cost to play this, reveal a card in your hand with cost 1 or less.

When this attacks, create a Quicken token.

You must have at least one other card in your hand with cost or less to pay for the additional cost of Flock of the Feather Walkers.
You may not reveal the same Flock of the Feather Walkers to itself to pay for the additional cost.
The Quicken aura token remains in play until destroyed.
A Quicken aura token may be represented by a small object such as a card sleeve or coin if a Quicken aura token card is not available.
You can not reveal a card for the additional cost, and then pitch that same card to pay the resource of Flock of the Feather Walkers. Paying resource costs happens before paying additional costs.
