Inkmoth nexus question

[Jdogtoocool]

So my opponent attacks with his {inkmoth nexus} I block with my own inkmoth nexus.  In response he activates {titanic growth} and {unnatural predation}. Not sure how it resolves but I'm thinking I take 5 poison counters, my inkmoth dies after placing an infect counter on his inkmoth.  Since his inkmoth still keeps the pump until the end of the turn it returns to being a land with a -1/-1 counter on it. Is that how it resolves?

Yea the counter would stay on the land

So he can't turn it into a creature anymore unless he wants it to die automatically

Correct, unless you somehow remove the counter.

Right
