I'm not quite sure where to put this, sorry if it's in the wrong place.

I haven't been seriously playing vanguard for too long and was wondering if there were some basic strategies to counter certain decks, like Revengers, Eradicators, ect?  I'm especially wondering about strategies against Link Joker (CBD), Genesis (Minerva), and Nova Grapplers (Beast Deities).

There's two method to beat CBD Deck.
1. Monarch Sanctuary Alfred or Ezel Scissor
2. MLB

For Monarch, i'm sure you already know it. if MLB, Keep them at 3 damages. Run 12 crits. Rear-guard on rear-guard, Swing MLB's 2 Crits to their vanguard. You'll get a great chance to get crits on late game, but if they guard your attack it's not a big deal since they can't use LB anyway. I won about 55% of my matches against LJ with MLB.
