Watch Out
This card involves continuous effects applied in layer order. Type changes (layer 4) are applied before ability changes (layer 6) and P/T changes (layer 7). The order matters — a creature that loses abilities in layer 6 can still get new abilities from effects applied later in the same layer.
This card has a static ability that applies continuously as long as it's on the battlefield. There's no trigger or activation — the effect just exists. Removing the permanent is the only way to stop it.
