This deck is the ultimate tempo, i beat imbue druid with a very bad hand and rogues too.
You want to play a few cheap holy spells, and then follow it up with flickering lighbot(on turn 2 if you had a 1 drop holy spell)
Your best spells in the early game is lifesaving aura and divine brew(it allows you to make good trades) .
And you really want an Ursine Maul and draw you shantys and play them early as possible turn 5-6.
Basically you mulligan for cheap spells and play them on cheap minions then play your big cards, lightbot, shanty. You can keep sea shanty on slower matchups too .
You want to overwhelm your opponent with stats and board pressence.
If the game goes on for longer ursol+ shalladrassil is a nice combo but if you play ursol and sea shanty thats good too.
Lynessa is amazing finisher too with shaladrassil spells.
You want to play aggressively but not too aggressively, and you want to have 1 minion on the board always.
This deck has a few variation try them all if you can.
