TYPE OF COLLECTORS Same as other Pokemon collector items like LEGO legendary Pokemon items, plushes, etc, Pokemon TCG cards are collector's items
The full texts of these abilities are "At the beginning of the monarch's end step, that player draws a card" and "Whenever a creature deals combat damage to the monarch, its controller becomes the monarch." If the triggered ability that causes the monarch to draw a card goes on the stack and a different player becomes the monarch before that ability resolves, the first player will still draw the card
Plus, its shiny form is an incredibly unique coloring, replacing its dark blue body with a grayish black
The only missing piece would be some sort of healing mechanic where the -1/-1 counters are removed via another creatures activation or similar ability
Many of these cards are going to be harder to find, but you should be able to lay a hand on some of the cards from this set
