Casting Deck of Lunacy more than once doesn’t seem to have any effect?
Tested in current TB. Played multiple DoL - only kept getting 5 mana spells reduced to 2.
You replaced your 2 mana spells with 5 mana spells that cost 2. Then you did the exact same thing and replaced your new 2 mana spells with new 5 mana ones.
it could if you get the beast that shuffles spells that are cast into your deck, but that might be a little overboard and remove the ability of going all spells in your starting deck.
It goes by the current mana cost to decide what to turn them into, not the original. So, a Fireball turned into Mask of C’Thun for example is seen as a 4 mana Spell since it costs 4 mana at the moment, which then gets turned into an originally 7 mana Spell that still costs 4 mana.
Note that this also means if you used Incanter’s Flow before and later on use Deck of Lunacy, your Spells will transform accordingly (AKA Fireball turns into a 6 mana Spell costing 3 rather than a 7 mana Spell costing 4 or 3, since its mana cost is 3 at that moment).
Once seems enough. Just had a mage spam me with 3 Earthquake spells in a row because of this op card.
