Elnxida on Cost Reduction Cards

1 year ago

I've noticed a few* omissions, namely effects that let you pay an alternate cost - which can be less than the regular cost (Zombie creaturess: Rooftop Storm) or reduced by other effects (Samurai: Kentaro, the Smiling Cat).

*Yeah, so I decided to do a proper search and it bloated into more than a "few"... Sorry for the wall of text, but here you go!
