Planes pendientes

For the first mode, you choose which card you'll be allowed to play as the ability resolves. The other card will remain in exile indefinitely.

If you choose the second mode, you choose whether Heroes' Hangout has one or two targets at the time you cast it. If you choose two targets, each of them get +1/+0 and gain first strike until end of turn.

You must follow all normal timing rules when playing a land or casting a spell this way.
