Seasons
Must you hold the crystals and energy a summon costs, or only have them available?
The rulebook says summoning costs are paid by discarding energy or crystals.

You must pay them, and you cannot summon without them. The cost is discarded from your reserve or paid in crystals, so you cannot go negative to pay it. This also covers a cost that makes you lose crystals.
