- The ① effect can activate and resolve while "Skill Drain" is applying.
- The ② effect can target a token monster. (in which case you still draw, and the token is destroyed).
- If the ② effect is activated, the other target must be face-up to be banished. (This card doesn’t need to stay face-up to be banished. If either isn’t banished, none are banished; no cards are drawn).
