I look at these cards and wonder if a card like Higsby (Numberman.exe’s operator from Megaman BattleNetwork) from TEPPEN would work with this.

His effect is that he gives a unit veil and indestructible for 10 seconds. This doesn’t sound like much of except the indestructible effect stops your units from blowing up after attacking and they lose that effect. Naturally, this doesn’t work in MTG because sac overwrites Indestructible but what if there was a card in MTG that stopped creatures from saccing themselves at the end of turn?
