Many Hearthstone players have expressed their dissatisfaction with this card’s rarity. This Mage minion summons another random minion that costs 3 mana, which is a big deal -- especially on Arena. But maybe this is exactly what Blizzard was going for -- to help new players progress faster with the help of strong and cheap cards.
It is obvious that this common minion is a tad overpowered, and imagine the combo with Brann Bronzebeard that triggers the Battlecry twice. In any case, you will see this card played everywhere -- in Standard, Wild, and Arena -- that’s for sure.
