Epic experiment

[Kmodad444]

So how does epic experiment work with cards with overload, can you cast them for their overload cost? Or can you cast there overload cost for less? How does this work exactly?

As said in the thread about snapcaster mage and overload, overload is an alternet cost and not a spells mana cost.
So epic experiment wont cast overload since it specifies mana cost and not overload cost.
