original pokemon cards first edition Custom Holo Charizard Blastoise Venusaur 151 1st Edition (TCG) - Bulbapedia,

You cant pay more loyalty than the planeswalker currently has

If it has an ability that causes other players to lose life or other damage that isnt combat damage, this doesnt count either

But it's uninkable, which means you are committing to playing this card at some point in the game, if you draw it

A larger number of colorless cards in Magic are artifacts, but there are also colorless nonartifact creatures, colorless instants, colorless sorceries, and even some colorless planeswalkers

I also notably did not include any red bombs that require 2 red mana to play

As a player casts an omen card, the player chooses whether they cast the card normally or as an Omen
