Flying, trample

Falco Spara, Pactweaver enters with a shield counter on it.

You may look at the top card of your library any time.

You may cast spells from the top of your library by removing a counter from a creature you control in addition to paying their other costs.

When Spara's Bodyguard enters the battlefield, you may choose a creature card in your hand. If you do, it perpetually gains "This creature enters the battlefield with an additional shield counter on it." Otherwise, put a shield counter on Spara's Bodyguard. (If it would be dealt damage or destroyed, remove a shield counter from it instead.)

At the beginning of each combat, Spara's Bodyguard gets +1/+1 until end of turn for each shield counter among other creatures you control.
