As important and sought after as the Pokmon trading cards are, certain Pocket Monsters on cards that are popular to collectors are: Bellsprout Blastoise Bulbasaur Charizard Charmander Clefairy Dark Muk Eevee Gastly Hitmonchan Ivysaur Ledyba Lugia Machamp Magikarp Magneton Marowak Meowth Mew Mewtwo Nidoran Ninetales Oddish Omanyte Pikachu Poliwrath Ponyta Primeape Raichu Rayquaza Sandslash Scyther Seaking Squirtle Umbreon Voltorb Wigglytuff Zapdos Other Pokemons include: Poipole, Naganadel, Stakataka, Blacephalon, Grookey, Raboot, Cinderace, Greedent, Morpeko, Dracozolt, Overgwil, Kubfu, Cursola, among others
The last throwback I want to mention also happens to be the fourth most valuable card (pre-orders) in Tarkir: Dragonstorm
If the target noncreature spell is an illegal target as Glen Elendra Guardian's last ability tries to resolve (probably because that spell already left the stack due to another effect), it won't resolve and none of its effects will happen
Morophon provides creature cost reduction and fixing, so a good strategy is to include color-intensive cards like Mantis Rider (free with Morophon) or Reflector Mage in a human tribal deck to obtain a better mana discount
Other variants aren't quite so pricey, with the original version from the first Commander product going for $46 and the Mystery Booster variant (easily identified by the big symbol in the rules box) still selling for $37
So, almost every creature you ramp out will net you an extra card, often for no mana
