When you draw, youll create a 1/1 blue Tentacle token with Watcher, which will trigger Undercurrents and let you draw again

SR Super Rare Pulao, Wind of the Yang Zing X WIND Level 1 [ WyrmEffect ] ATK 0 DEF 1800 When this card you control is destroyed by battle or card effect and sent to your Graveyard: You can Special Summon 1 "Yang Zing" monster from your Deck in Attack Position, except "Pulao, Wind of the Yang Zing"
As a result, if you can kill the (usually heavily guarded and well protected) general, you can gain such an absurdly huge advantage that, even if your opponent is in an amazing position, you can still win
