Pokmon TCG Live is a title whose gameplay is similar to Yu-Gi-Oh
In another exception, some planeswalkers can be used as your commander, but only if the card explicitly says this card can be your commander on it
I'm generally pretty dead set on the devotion cards in the deck staying for flavor and fun reasons (even though Erebos, God of the Dead isn't spectacular)
Equipment precons are nothing new, but what makes Limit Break special is its encouragement to spread your Equipment to multiple creatures, instead of keeping them all on one
Cards like Sidisi, Brood Tyrant fill your graveyard at a consistent rate, so you have more possible targets for reanimation
Then, every time the equipped creature attacks, you can search your library for a basic land card
