Whenever a creature you control becomes blocked, create a tapped and attacking 1/1 black Illusion creature token. You may have that token exchange places with the blocked creature. (They switch which creature is blocking or being blocked.)
Whenever a creature you control blocks, create a 1/1 black Illusion creature token with "Sacrifice this creature: Target creature gains indestructible until
end of turn," blocking the same creature.
