Entanglement

[Chapuz]

Synergies with kittens, Catapult, Fungi, immolation, probably  stuff and CC in general.

I would make it cost 1  / 1

Don't like removing upped having a non cost

Fungi is a place where a quanta sink exists. For soul catcher is probably better

Raises question: do we really need a rainbow soulcatcher? Have not been feeling a lack of quanta production methods

Can change to "when killed during opponent's turn" instead. Then drop the cost significantly... like maybe 2 / 1
Then you have a deterrent / soft anti-cc.
You could tweak the wording to allow this to trigger off of shields and poison as well possibly. That would be quite nice.

Fungus paying for themselves and 2x immo  quanta is what I was seeing tempting. Catatitans can also be reliably rainbowizable. Metamorphosis and Lockets are making quanta generation more dynamic, you can have fast  for Catapult and 1 Titan and then generate other quanta

[OdinVanguard]

Its not that it doesn't have uses, its that it might be a little TOO good. I.e. its way overshadowing soul catchers I think.

Soul Catchers are more for the 0/1 cost creatures, this ones are to use the death of the expensive ones
