Combos Utilizing Nettling-Imp

once you have moat out, you can force your opponents to attack with one of their creatures and they will die. if moat isnt out yet, the royal provides you some time

figure it out

tap the nettling imp to make one of his creatures attack. then tap the sorceress queen to make his guy a 0/2 and block it with baron. you kill one of his creatures and baron gets +2/+2

Put Shackles on a tapped creature, then use Nettling Imp to force it to attack and since it cant then its dead!!!

pay the chant's kicker so they can't attack, use the ipm's ability

just twiddle your opponents creature, so they're tapped, then force it to attack, it can't, it's dead.

cast backfire on one of your opponent's beefy creatures, and force it to attack with nettling imp to deal your opponent damage. ideally, have some means of preventing the damage to yourself.

Force creature to attack and destroy before damaging

use mind games to tap their creature, paying buyback. force the creature to attack. it cannot, because it is tapped. repeat as necessary.

Make a creature attack with the nettling imp, make this creature a 0/2 with the sorceress queen, and kill it with the sengir vampire which will have a 1/1 counter easily thanks to that.
