Ambassador Blorpityblorpboop

Although Ambassador Blorpityblorpboop’s last ability considers the power and toughness stickers of permanents you control, the card itself is not considered to be stickered unless there’s actually a sticker on it.

Ambassador Blorpityblorpboop counts all power and toughness stickers on all permanents you control, even if those power and toughness stickers don’t currently have any effect (possibly because you placed another power and toughness sticker on the same creature).

The base power and toughness change doesn’t end at end of turn; it lasts indefinitely, until Ambassador Blorpityblorpboop either leaves the battlefield or its base power and toughness changes again from another effect (for example, a power and toughness sticker being placed on it or its ability triggering again).
