My piece of advice is that whenever you think a card has an interesting effect, pick it up even if there are cards that can do something similar better or even if you dont see immediate use
The Mewtwo & Mew GX from Sun and Moon Unified Minds paired two of the most iconic Psychic-type Pokemon in franchise history on a single card, creating a piece that resonated powerfully on both the collecting and competitive levels simultaneously
As a 2/2 artifact creature with a creature token generation and targeted removal power, Robot Chicken was a relatively powerful card
Disregarding that insane value, assuming youre in mono-green or have excellent fixing in Standard, it also has an activated ability to transform
Countering a blue spell or destroying a blue permanent is a tad situational, but its super effective when used against the right blue control deck
The final card I am cutting is Rashmi, Eternities Crafter
