(Choose any number of permanents and/or players, then give each another counter of each kind already there.) Even the small wounds let hope bleed out
Cards such as Accursed Marauder, Fleshbag Marauder, and Merciless Executioner all accomplish this, and have a mana value of three or less, allowing Squall to bring them back and force another mass sacrifice every time it connects for damage
[1] During the End Phase, if a monster has been destroyed by battle this turn: You can Special Summon this card from your hand or GY, then if "Invincible Demise Lord" has been destroyed by battle this turn, this card's ATK becomes 3000, also it cannot be destroyed by effects
Once you have the Salvage, you can just discard it and dredge it back, over and over, similar to how Swans of Bryn Argoll was used nearly a decade ago
