Gemstone Caverns

If I mulligan and start with a {gemstone caverns} in my hand can its ability still activate?

[Gorzo]

Yes. Your "opening hand" is the cards in your hand of cards you decide to start the game with, after any mulligans.

Great thanks

[Jdogtoocool]

Also can you wait to activate the ability before the opponents end phase?

[scarsabrex]

No. It says you may begin the game with it not play it during the opponent's turn.

[Jdogtoocool]

Yup that sounds about right thanks and happy holidays
