Flowstone Shambler⁣ - Stronghold⁣ (Common)

Flowstone Shambler is a 2/2 creature for {2}{R} that can pump its power at the cost of toughness until the end of turn. This ability allows it to adapt to different combat situations, potentially taking down larger threats or serving as a blocker. It fits well in aggressive red decks that aim to apply pressure, but its reliance on mana for power adjustments means it can be vulnerable if not used carefully.
