There's no 'foreshadowing' of upcoming better psychic support, it's in this set. Malamar is basically the best kind of support you can ask for, ability based energy recovery on a stage 1 is almost always extremely good. Mystery Treasure is good now, great later. It increases the probability of a t1 Brigette while also providing more outs to your purple type evolution cards at a lower cost than ultras.
One thing I'm going to mess around with for sure is a Malamar/Dragalge/Victini deck. I used to love messing with Mega Mawile and this seems like a less janky way to play that. Shame they had to put it so comfortably in Zoroark/Golisopod OHKO range.
