It doesn't care if you take spells or creatures, you get a reward
If you can get this to stick around and use it in a deck with some cheap equipment, this can be a real house
Many cards have rules text on them that allows them to use an ability, with a special effect
Additionally, if you have a full party, youll get to put a +1/+1 counter (as well as giving them deathtouch) on each creature you control at the beginning of combat on your turn
I'm not sure if it was restricted out of fairness, or if they actually thought the card was overpowered at 2 mana (can't imagine the thought process, when crusade and bad moon were fine, but then, they restricted gauntlet of might, so maybe they didn't like red guys getting pumped!) Rukh egg looks fine today, maybe even pretty weak
So far, theres no information on when this precon will actually be released, or what the full decklist looks like
