Mimikyu is definitely a staple for Malamar, a tick of Shrine/Giratina/Spell Tag give you permanent ability lock and free up the power plant space, freeing up space for the Marshadow that you would otherwise need to use against Chaos Vortex. When we get back DCE, spread decks like Weezing will love it too.
I kinda wish Vaporeon, Jolteon, Flareon, Leafeon and Glaceon were getting tag team cards as well. Maybe with Suicuine, Raikou, Entei, Shaymin and Kyurem respectively. Probably not going to happen though.
