basicly blue is a defencive color but it works for beatdown too here is a 
deck to prove it 
                     
                                       merfolk assult 
                              4x Lord of atlantis 
                              4x merfolk of pearl trident 
                              4xCoral Merfolk 
                              4xreef shaman 
                              4xMefolk looter 
                              4x Artic merfolk 
                              1x root water thief 
                              4x ceta dicsiple 
                              4x levethian 
                              4xcounter spell 
                              4x time ebb 
                              4x ancestral memories 
                              3x inspiration 
                              20x island 
    the strategey for this deck is to get a bunch of little merfolk out 
earley play counter spells and time ebb to by time, the trick to this deck is 
get al4 lord of atlantis 
out so even merfolk of pearl trident are 5/5"s and have island walk! if your 
aponent doesn"s have any islands out use levithian to give them flying!if 
thats not enough 
try this last part its a reef shaman, ceta diciple combo tap reef shaman to 
turn an island into a mountain and use ceta diciples abilty ability to put on 
the final touch. 
                   i hope this helps people get a clue 
                   p.s. if your not drawing the right cards use merfolk 
looter and inspiration thats what theyre for
