Pray for a miracle

[munchkin_account]

Sorry to bring this thread up again. I was thinking of trying to play using epic rules and got a question about this feat.

The latest Epic Munchkin pdf reads:

"Cleric: Pray for a Miracle. At any time, even during
combat, you may discard two cards, from your hand
OR the table, to take the top card from the Treasure
deck face-down into your hand. If it is something you
can use, you may play it immediately."

So does "using" in this case include playing new gear? E.g. I'm fighting a monster, use this ability and get a +2 armor. Would I be able to equip it during this fight if I have a free armor slot and get the +2 bonus immediately?
