The Scarab Kid

Whenever another nontoken creature you
control dies, choose one —
• Put a loyalty counter on target common-rarity Planeswalker you control.
• Put a +1/+1 counter on The Scarab Kid.
When The Scarab Kid dies, put X loyalty
counters on target planeswalker you control,
where X is The Scarab Kid's Power. Shuffle
The Scarab Kid into its owner's library.
