Creature â Elf Druid
When Peema Aether-Seer enters the battlefield, you get an amount of (energy counters) equal to the greatest power among creatures you control.
Pay : Target creature blocks this turn if able.
You canâ€™t pay more energy counters than you have.
The target creature blocks only if itâ€™s able to do so as the declare blockers step begins. If, at that time, the creature is tapped, itâ€™s affected by a spell or ability that says it canâ€™t block, or no creatures are attacking its controller or a planeswalker controlled by that player, then it doesnâ€™t block. If thereâ€™s a cost associated with having the creature block, the player isnâ€™t forced to pay that cost. If that cost isnâ€™t paid, the creature wonâ€™t block.
The controller of the target creature chooses which attacking creature that creature blocks.
The amount of you get is determined as Peema Aether-Seerâ€™s first ability resolves. If the greatest power among creatures you control is somehow negative, you donâ€™t get or lose any .
Keep careful track of how many energy counters each player has. You may do so by keeping a running count on paper, by using a die, or by any other clear and mutually agreeable method.
If an effect says you get one or more , you get that many energy counters. To pay one or more , you lose that many energy counters. Any effects that interact with counters a player gets, has, or loses can interact with energy counters.
Energy counters arenâ€™t mana. They donâ€™t go away as steps, phases, and turns end, and effects that add mana â€œof any typeâ€ to your mana pool canâ€™t give you energy counters.
Energy counters are a kind of counter that a player may have. Theyâ€™re not associated with specific permanents. (Other kinds of counters that players may have include poison and experience.)
is the energy symbol. It represents one energy counter.
