Cunning of the Six Samurai X SPELL Quick-Play Send 1 face-up "Six Samurai" monster you control to the Graveyard, then target 1 "Six Samurai" monster in either player's Graveyard
I recommend playing 3 of her, with 1 or 2 Fleur and zero, or one Punishment
All of the Level 5 or lower monsters, except "Aegirine", are also able to banish themselves with their second effects if a face-up WATER monster the player controls is destroyed, which works well with both "Icejade Cradle", so it can search out the same copy that just banished themselves, and "Icejade Erosion", which can be used to disrupt the opponent's plays by destroying an "Icejade" monster to negate the effects of an opponent's face-up card
I especially love Squirrel Dealer, which is literally three critters in a trench coat
Just the core benders and bruisers that are ready to make a splash at your next Commander night
