Fake Your Own Death is also a solid combat trick, but unfortunately black creatures do not have too many great ETB triggers
No, creatures with Menace must be blocked by two or more creatures
For examples Lightning, Security Sergeant needs to remain on the battlefield, Grolnok, the Omnivore can only add croak counters if the card went directly from the library to the graveyard (usually because it was milled), and Kaya the Inexorables emblem only triggers at your upkeep and looks at legendaries
The tokens can otherwise be used to stall for late-game commanders like Damia, Sage of Stone, and as Aristocrat fodder for Mazirek, Kraul Death Priest
First of all, it allows you to retain the previous levels type, allowing you to continue to hit for weakness
