This deck has only one purpose, controlling one or both side of the board, then place one or two "Luduans", protect them, and win the game by card advantage, control of the board, and finally pressure and oppressing.
Here are all the combos and synergies in that deck:
-Since the goal of the deck is to control one or both side of the board, meaning that u'll need to place 2 lands for double collecting and if possible 1 blue land beneath the opponent well, i put 3 "Water elemental" and also 2 "Prophet of tides".
"Prophet of tides" are really important, let's suppose that u are starting the game in 2nd position, u play your "Explorer" card on one side of your orb then a blue land at side. On the next turn you play a second blue land just above the first one , then u summon "Prophet of tides" on that second blue land, and so u can go directly beneath the opponent well with him and ensure a place to summon "Luduan".
-Since you are supposed to harvest faeria with "Luduan" during the game, your 3 "Wavecrash colossus" will cost 4 faerias very fastly, but this is the same for "Azure wisp", they will also grow very fastly.
-And on the same occasion, your 2 "Triton sanctuary" are also supposed to give u a lot of faeria because your "Luduan" double collect, and also because you play a control deck, meaning that u'll collect on 2,3 or 4 wells.
-i added 2 "Triton chef", it's a cheap creature that will collect faeria and also provide you 2 "Triton banquets", very useful to play on your "Azure wisp" and grant them mobility, but also on "Wavecrash colossus" or even "Prophet of tides". You can't imagine how this card has a big potential of surprise, above all because the opponent often forget that u've got one in hand given by "Triton chef" earlier.
-"Aurora, myth maker" is also important, especially to protect your "Luduan".
-Don't forget that if everything goes well, you'll gain 1 or 2 blue cards costing 2 less each turn. i often had another "Aurora, myth maker" in those blue cards.
-Finally to control the board and keep your "Luduans" alive i put 3 "Crystal flowers", 3 "Frogify", 3 "Queen's guard" in addition to the "Aurora, myth maker" and the blue cards given by "Luduan".
Mulligan: There are many cards to avoid, like "Wavecrash colossus", "Azure wisp", "Triton sanctuary", Crystal flower" or even "Frogify"..
I wish you a nice and respectful fight!
