[2019] New Mage Spell: Conjurer's Calling

Once minions are on the battlefield, their Costs are treated as the normal Cost for their card. This applies to Giants, discounted minions, and other 1/1 things. So if you have Dorian on the battlefield and you draw a 5 Cost minion, even though the minion on the board is 1/1, the Cost for that minion is 5. If you cast Conjurer’s Calling on the 1/1 minion, you’d end up with two normal sized 5 Cost minions.
