This looks really fun. I would put in paradox haze, though. And if you're gonna be playing three colors, I'd throw in Teferi's moat, at least as sideboard. Otherwise, your deck might be too slow. I've never been a big fan of Beacon of Immortality because of the hight mana cost. Another idea is throwing in an Isochron Scepter for fun.

Also, you have no decent creature removal. While you're busy getting lots of land with nothing to play, your opponent can bring out a couple small creatures and attack you every turn.

Any comments? please? I'm currently running a similar deck without the pandemoniums. It's just a red elemental aggro, and it does well against most decks, even fast elf aggro. The biggest problem is that I don't have giant creature removal and no enchantment removal.

I would take out 4 Plover knights and 4 Divine Transformation. You only have 18 plains, you shouldn't be playing Plover Knights.

Instead, I would put in 4 Knights of Meadowgrain and 3 Thoughtweft Trio, and another Wizened Cenn. You may also think about putting in Coat of Arms. Militia's pride is going to pump out those kithkins, so coat of arms will buff all your creatures up.

i don't see why you put traumatize in your deck. It doesn't seem to be doing anything for you. I'd put in a couple cruel edicts and megrims.

artifacts! whee! looks like fun.

yes, definitely add Sygg and some multicolored mana. Also Sideboard some counters in. Most merfolk decks i've seen don't carry any counters, but one wrath of god or damnation and it's GG.

smallpox seems like it would work well with your deck. And yes, you should put in Urborg, Tomb of Yawgmoth if you have one. That will make your beetles unblockable.

Definitely take out Radha. you can only use her red mana to cast instants, and you have no instants. If you don't use up that mana during the combat phase, mana burn.

Blue/Green should be labeled UG, not BG, just to let you know. BG is Black/Green in the magic world.

Yea, I think O Rings would be useful against those random threats, like planeswalkers or Stuffy Dolls or Teferi's Moat. Definitely a really solid deck.

Here are a few suggestions:
1. Take out red and blue. The deck can be stronger if you focus on white, since you barely have any red or blue cards anyway.
2. Add in that white enchantment that gives all your creatures +1/+1.
3. At the moment, it looks like your strategy is to use flying creatures to attack with some random creatures to block. I recommend adding Serra's Avenger. Also, some low cost first strike creatures and creature destruction will help.

Having 12 "links" seems an awful waste of deckspace when you only have 4 creatures.

I recommend putting in Pestilence. Pestilence + Stuffy Doll + Pariah is an awesome combo. Stuffy prevents pestilence from being sacced, Pariah redirects all damage to stuffy to your opponent, and pesilence destroys all your opponent's creatures. If you have more than one stuffy out, w00t

I would switch out Mistbind Clique, for the obvious reason that you have no other faeries in your deck, thus you can't use it to tap all your opponent's lands and you can't use it as a creature either.

Instead, I'd use Surgespanner.

To make Wanderwine Prophets effective, you must make your creature unblockable and have merfolk to sac. I would put in Protective Bubble and Summon the School.

I would take out the whitemane lions for Serra Avengers. The lions will slow you down.

If I put in Sudden Spoilings, I'd probably take out what... cloud sprite?

I think I'll take out the cloud sprite, put in 2 sudden spoilings, 1 wydwen

i would put in essence sliver for the life gain.

I made a deck like this. my favorite combo in it was:
incandescent soulstoke ability to bring out nova chaser, champion the harbinger and attack. end of turn search for another nova chaser

I may need help on my sideboard cards. Any suggestions are appreciated.

Wow, too many slivers to choose from!

Definitely keep 4 Sinew, 4 Gemhide, maybe more essence slivers than you have now.
Hivestone and your non-slivers seem to be a waste of space.
Dolmen Gate is definitely good.

Besides that, I'm not too sure, because I've never made a sliver deck.
