Split Personality

Whenever a nontoken creature enters the battlefield under your control, you may pay {1}{b} and/or {1}{r}. If you paid {b}, create a token
copy of that creature except it gains deathtouch, menace and haste. If you paid {r}, create a token copy of that creature except it gains first strike, trample and haste. Sacrifice those tokens at the beginning of the next end step.
The mind is a fickle thing.
