How is your current list performing? I'd only run 2x Harbinger of the Tides, because I hesitate on cutting the rest of the Phantasmal Images

may actually just be the new merfolk. Many of its slots are filled with better options than in merfolk decks. 1drop Champion of the Parish gets huge fast, much better than Kumena's Speaker. Silvergill Adept is replaced backwards by Meddling Mage and Kitesail Freebooter. Both Thalias do what Spreading Seas does in merfolk, just with a body tacked on, Reflector Mage is a much better Harbinger of the Tides, and Thalia's Lieutenant is just a great lord. Mayor of Avabruck  Flip is mediocre, but hey. And finally: if merfolk had an on-tribe manadork like Noble Hierarch with a pretty big upside to boot, they wouldnt hesitate a second running a playset.Now that 12 5color-lands allow for a painless, consistent mana base, I see no reason to run merfolk over 5c humans, to be honest!

Please leave a comment and not just a +1. Looking for advice on this new control, vs the current standard meta.

I like where this is headed. I would like to as well suggest some bigger meat on the table as 1/1s can take a while.

While keeping with the flash and budget themes, I would suggest:

Obstructionist in particular could finish games in a hurry.

If you wanted to break from the theme a bit, but lend some inevitability to the match, I would suggest the new Blue God:

He won't break the bank, and gives you a lot of late game potential. Plus he is immune to most non-exile removal. Downside, no flash.


Another route to take could be ninjas. You are already halfway there with memnites. They would fit your curve, but still require mana on your turn, so I understand why you went the way you did.

+1 from me.

Harbinger of the Tides is not Standard legal.

Harbinger of the Tides legality

Neither are a lot of other cards you have in this deck.

Look up the top, just under the name of this deck.

See how "Standard" has that little " * " next to it? That indicates that your deck isn't Standard legal.

Scroll down until you see "Highlight illegal cards" on the right side of this page.

Click on that and it will show you which cards in this deck aren't legal for Standard.

If you scroll back to the top after doing that, all the names of the illegal cards will be shown in red.

If you meant this deck to be Modern, and not Standard, I can't help you.

As I say on my profile, I only help with Standard decks.

There are some pretty cheap dual lands you can add here to make the deck more consistent-

Yavimaya Coast

Lumbering Falls

Temple of Mystery

Thornwood Falls

Looks like you already have Master of the Pearl Trident which is great. I suggest picking up Lord of Atlantis as well and then coupling it with Spreading Seas or Sea's Claim to mess with your opponent's mana and make your whole team unlblockable against non blue decks with islandwalk.

Cancel is quite bad and there are plenty of cheap upgrades you can choose from something simple as adding a scry with Dissolve or going more narrow and efficient with Spell Pierce, Unified Will, or Mana Leak

Typically Merfolk decks play Aether Vial to power out multiple cards a turn, but they are quite expensive so since you are running , I suggest Collected Company

Other good Merfolk options

Before anything thanks for taking time to post a reply!

This deck is not built to be played as a Blood Moon list with Madcap Experiment - if that was the goal, i would ditch Platinum Angel without a second thought, to play Platinum Emperion.
The deck is a combo/prison deck built to abuse Platinum Angel
So lets take pros, and cons compared to the emperion:
- if the creature leaves the battlefield there is a big chance of game loss on the spot.
- it dies to Dismember
- deals less damage when it gets in
+ has flying to prevent getting chumped
+ prevents game loss to infect counters (that is relevant due to Inkmoth Nexus)
+ can win by "milling", after the enemy gained infinite life
+ Pact of Negation becomes a free counter
+ Glorious End - "the jank" - becomes Time Walk / exile the stack if i have angel in play by next end step.
+ Earthquake becomes Bonfire of the Damned when the angel is in play

Otherwise Earthquake is just a boardwipe, that costs me life, and one that can be redirected to planeswalkers, but i would not call it bad due the combination of being able to cripple decks that go all out on the board early, and being a late game win condition.

I agree that Abrade looks as questionable as a card can get - if we are talking about modern.
However its a must have for me to have ways to deal with Grafdigger's Cage & Aether Vial. The problems caused by the former are pretty obvious, the latter creates enormous problem by putting in play stuff like Flickerwisp or Harbinger of the Tides.
I play abrade because its the cheapest creature removal that doubles as artifact destruction in colors of the deck.
There may be an argument to replace some of them with Kolaghan's Command - but i fail to see how Lightning Bolt could fill the same role.

I am also really curious what is behind your judgement regarding Pieces of the Puzzle - in my opinion its one of the best cards that have been printed lately. And its exactly what i want to do on turn 3.
Drawing my counterspells, or madcap experiments, to cast when i get to 4 mana on the next turn. And it can be recast with our good old friend Snapcaster Mage for 5 mana.

So Glorious End...
Time Walk, or countering Emrakul, the Aeons Torn, Supreme Verdict, or all copies of Grapeshot from the stack, or the Liliana of the Veil's -6 when the opponent cashes in, is not something i would call "jank", or unplayable.
Of course that is only my humble opinion.

Tamiyo doesn't really do anything in this deck; Play Future Sight instead of Magus, it's harder to deal with; Run counter spell instead of Hindering light, you know you'd rather counter that Wrath; Riptide Director is a worse Azami, Sage of Fables however buffs most of your dudes and allows for some interesting things; If you are gonna run Mystical tutor play an instant or sorcery worth it being in the deck for.

Cards worth adding:
