professor research pokemon card full art Professor's (Professor Magnolia) | Sword & Shield You may only play 1 Supporter card during your turn Professor's Research (Professor Magnolia) SR

It tells you that you can activate his abilities not only at instant speed, but also during every turn, not just your own

The best case for all of these cards is probably Edric, Spymaster of Trest, which held steady at around $4 with very fringe legacy play, until it ended up winning a SCG open last April and spiked to $15 overnight (before getting reprinted in Conspiracy a few months later and dropping dramatically)

Crypt Rats Crypt Rats is a reprint with new flavor text from Ghoulcaller Gisa, a necromancer from the Gothic Horror plane of Innistrad

This lets you build a resilient swarm of tokens that can deal lots of damage quickly

Taken at face value, Shuko is a pretty mediocre equipment card from the old MTG set Betrayers of Kamigawa
