As an additional cost to play this card, bury a follower that costs 5 or more, give your leader -3, and discard a card.
----------
Look at the top 7 cards of your deck. You may summon a follower from among them. Put the rest on the bottom of your deck in any order.
QMegaera, the Indignant has the ability "This card can’t be destroyed by abilities." If I play Golem Squad and choose to bury Megaera, the Indignant as part of the additional cost, does it remain on the field?
ANo. Burying a card is different to destroying it.
QIs the cost of an evolved follower the same as its unevolved form?
AYes, it is.
