A good rule of thumb is that bulk cards are worth about 10% of the value of individual cards in the same set
Sure theres instant win combos, such as Quest for Pure Flame, but theres also fun with planeswalkers, proliferate, or cards that put counters everywhere
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
While its too early to call, Ragost is definitely a contender for the Hot New Commander title in Edge of Eternities
It'll just be a matter of experimenting to find the right combination
