Rotom V is also excellent for these decks, as it can end the turn by drawing three cards, making players able to set up for the next turn
The card is an enchantment which lets you draw an extra 2 cards at the beginning of your turn
If that wasnt bad enough, it can last up to three turns thanks to the summoning requirement of the card being 3 monsters, and the cost of the effect being a measly one XYZ material
You can play him on curve much much more safely than most planeswalkers because his effective cost is just two mana (normally, it can be a lot less if you have things that tap for more than one)
Artifact-fall effects from cards like Moon Girl and Devil Dinosaur can double up on playing card draw artifacts
The home of Pokmon produced most of the grails, and its still the cheapest, deepest market for the cards you can actually afford
