Sea Dragon Marine Corps (Standard)

The goal of the deck is to overwhelm the opponent with both unblockables that continue to gain strength and by generating Hexproof Merfolk tokens. There is fairly limited removal, because this is intended to be a fast deck and less tempo oriented than most blue + color decks.

River Sneak, Deeproot Waters and Hadana's climb are essentially the keystone cards of the deck. Hadana's climb synergizes well with a deck that already generates +1/+1 counters and its transformation can deal a lethal blow. Whereas Strength of the Pack synergizes with the token generation. The only way to deal with the hexproof Merfolks effectively are with board wipes and the Dive Down typically deals with any removal.

The key to utilizing this deck effectively is managing mana, both your own and your opponents. I tend to opt for a slower start if I suspect removal out of the gate.

RG dinosaur decks can be a problem if you don't take them out early. The mechanic of doing 1 damage to all creatures can wipeout your merfolk tokens before you get counters on them and they have removal mechanics that are based on summoning more creatures, so they will often outpace this deck. You have to target specific cards with the limited removal in the deck and try to win it before they have a chance to build up.
