Its attacks were no longer as limp and weak as they had been at the start. The "Nine-Lived Cat Demon" could no longer kill it in a single blow.
This was the "House and Death Pact"!
As long as an allied creature died within the bounds of the "House," it would become stronger after being revived.
Although each increase in strength had its limit, when paired with the "Cat Returned from the Underworld," which could revive without limit, it meant constant growth!
Under normal circumstances, even if the opponent did not know the effects of the "House and Death Pact," they would stop killing the "Cat Returned from the Underworld" once they noticed something strange.
And that was when a Magitech Card capable of driving the opponent's Magic Spirits into "frantic confusion" was needed!
Sara's deck had a corresponding system.
The infinite revival system centered around the "Cat Returned from the Underworld" was one part of it.
In addition to its core Ultimate Move, "Return from the Underworld," the "Cat Returned from the Underworld" also possessed "Shadow Bind," which could control targets over a wide area; "Shadow Escape," which could free it from control and traps; and "Shadow Fang," which could inflict considerable damage upon a target.
Unfortunately, it did not possess an Ultimate Move of the deathrattle type.
Otherwise, if every death could trigger a deathrattle curse, that would be truly damn satisfying.
