Is MLB good? Want to form a deck. Royal or shadow btr?

Comments please

mlb is good in my opinion damn rush but lack of rearguard. but sp is better in def and have more handsize using macha or skull witch. and normally will drag the whole game. lol just my opinion depend which one u like

i think that i does not matter which deck is better is how u use it
even if u have shadow but does not how to use it there's no point either right so i think u should start with a deck u are use too or know how to use

Ohhhh. Thanks. But MLB deck consist of what cards?
