It is also important to note that this is only an analysis of MTG cards, and the rules (and the stance from copyright holders) for Pokmon, Yugioh, or other CCGs could be different
Just remember, these are not tournament legal, so they're exactly like MTG Proxies you could make at home, and probably not worth gambling thousands of dollars to obtain.
Each monster your opponent controls loses 1000 ATK for each monster linked to it
Then you can spend two mana to make a swinging Rat gain deathtouch for the turn, which if you keep free when you swing, people won't want to trade down into, making it more likely you'll smash more face
Plus, you have a lot of ways to fight back out of the sideboard, including Mystical Dispute and Flusterstorm
In order to do that, you must place two Centerfrog cards on your opponents unoccupied monster zones
