I realize the novelty of having non-fantasy elements show up is a bit diluted with so many crossovers that MTG's had in recent years, but a real person is still going to be quite interesting, I think
In Tribal Elf decks, or unknown playgroups where you have no idea what you'll be up against, or you reeeeally want to get maximum value out of your Skullclamp, Reclamation Sage is better
Spinerock Tyrant is a 6/6 mythic flyer for (3)(R)(R) that brings a new level of utility to reds high-end threats
Open More Packs for Less Lets be real: chasing that Charizard can get expensive
Cloud Of Faeries The best classic faerie card (he's from way back in the "Summon Creature" days), this guy is essentially a free 1/1 flier that you can also cycle out for 2 mana if you don't need the extra creature
Its also somewhat similar to effects like cascade in that you dont know what youre going to get from seek until it ends up in your hand (unless youve built your deck in such a way that only one card can fit those requirements)
