... If I do not have space in my hand for the 2 copies of a spell with full mana that Repeated Reverberation makes, the whole game crashes. Even if I have space for one card in my hand, the game crashes because I do not have space for 2 cards.
I am running a Chandra deck with Dragon Hoard, and if I accidentally trigger Dragon Hoard before casting any spells, I end up drawing cards and crashing them game when Repeated Reverberation is cast.
I just need a better land that gives red gems and doesn't cause me to draw cards, but until then I need Dragon Hoard. :-)
When I say the game crashes, that is exactly what happens. No frozen screen, no staring at a locked image, the game shuts down.
