Tromell, Seymour's Butler

Legendary Creature — Elf Advisor

Tromell wants a deck that keeps making its creatures bigger turn after turn. It also works in a deck built around Advisors or Elves.

  • Mana cost2 genericgreen
  • Green ()
  • Power / toughness2 / 3
  • RarityRare

Each other nontoken creature you control enters with an additional +1/+1 counter on it.

1 generic, tap: Proliferate X times, where X is the number of nontoken creatures you control that entered this turn. (To proliferate, choose any number of permanents and/or players, then give each another counter of each kind already there.)

Wizards of the Coast 6 Jun 2025

If a player or permanent has more than one kind of counter on it, and you choose for it to get additional counters, it must get one of each kind of counter it already has. You can't have it get just one kind of counter it already has and not the others.

Wizards of the Coast 6 Jun 2025

If you proliferate multiple times, you don't have to choose the same set of players and/or permanents to get additional counters each time.

Wizards of the Coast 6 Jun 2025

Players can respond to a spell or ability whose effect includes proliferating. Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it's too late for anyone to respond.

Wizards of the Coast 6 Jun 2025

The value of X is determined only once, as Tromell's last ability resolves. To determine that value, look at the nontoken creatures you control and count each one that entered this turn. It doesn't matter if they were creatures when they entered or who controlled them when they entered.

Wizards of the Coast 6 Jun 2025

When you proliferate, you can choose any permanent that has a counter, including ones controlled by opponents. You can choose any player who has a counter, including opponents. You can't choose cards in any zone other than the battlefield, even if they have counters on them.

Wizards of the Coast 6 Jun 2025

While proliferating multiple times, players can't respond between proliferating the first time and proliferating the second time, and so on.

Wizards of the Coast 6 Jun 2025

You don't have to choose every permanent or player that has a counter—only the ones you want to add counters to. Since "any number" includes zero, you don't have to choose any permanents at all, and you don't have to choose any players at all.

Color identityEvery color of mana symbol on a card, in its cost and in its rules text. Your commander's color identity sets the limit for your whole deck: every other card has to fit inside it. A deck led by a green and white commander cannot play a card with any blue in its color identity.Open the full glossaryGPlayers write colors as letters: G for green.+1/+1 Counters+1/+1 counter decks put small markers on their creatures that make each one permanently bigger, and keep adding more every turn. Each +1/+1 counter adds one to a creature's power (the damage it deals) and toughness (the damage it can take).Open the +1/+1 Counters pageCounter ManipulationAdds, moves or multiplies counters already on permanents. It works on any kind (+1/+1, loyalty, charge), so the same card can serve very different decks. Karn's Bastion, Doubling SeasonOpen the Counter Manipulation pageCounter EngineAdds +1/+1 counters over and over rather than once. A counter here is a small permanent marker that raises a creature's power and toughness for good. It is not a counterspell, which is a different thing entirely. Something that adds them every turn makes your whole board bigger and keeps it that way.
