Go Zanz! 8)
IMO, super slow way to trigger death effects....
You can have 3 vultures, 1 bonewall, 2 graveyards. All powered by the cat. You just need 2 entropy per turn. Just use some pendulums.
It is super cheap (unupgraded-->1 quantum).
Woohoo for combos that work against 30 pillar opponent!
If instead of those 3 vultures, 2 graveyards, 1 cat combo, you fielded 6 Flesh Recluses (upped) or 6 Mummies (unupped), you'd be mono, doing shitload of more damage, and have much better draws in a way you wont be relying on your 1|1 creature to have a combo, or relying to draw all those stuff.
Let opponent kill your creatures if he can to fuel your Wall, while actually doing damage to the opponent. You dont really need Cat for it.
I'm not saying this card does nothing. I'm saying its effect is weak.
