I personally prefer Flood of Tears over Devastation Tide as well as Thaumatic Compass  ^Flip over Maze of Ith, but those are just preferences and you don't need to add them. Also Jwari Disruption  ^Flip and Khalni Ambush  ^Flip could be replaced with more efficient removal like Pongify and Rapid Hybridization.

@gingerthewritingdog:

Thank you for your suggestions. On the original list there are mostly cards which i already own.

Nevertheless i agree to Pongify > Jwari Disruption  ^Flip and Thaumatic Compass  ^Flip > Maze of Ith. What i like about the compass is that you can tutor for lands and gain the same effect as Ith AND tap for mana if your need to. The latter is definitely a worthy swap.

Don‘t you think Flood of Tears would be a more efficient swap for crush of tentacles?

With mostly high power creatures i thought Khalni Ambush  ^Flip would be a versatile removal or a land drop if you need one.

Housegheist I do think Flood of Tears is probably better than Crush of Tentacles, but I didn't suggest cutting Crush of Tentacles because it fits with the theme, but if you are okay sacrificing a bit of flavour and synergy, then flood of tears is probably better than crush of tentacles. Also I do agree that it is nice to have some versatility in Khalni Ambush  ^Flip, especially with the landfall subtheme, so it isn't really a necessary cut.

@gingerthewritingdogClaire I do not think that Flood of Tears would be a cut in theme. The name and th artwork fits :) I added it to my wantlist :)

What do you think to swap Gush for Guardian Project?

I think Gush is a powerful card, but guardian project will probably provide a lot more card draw over the course of the game, while gush is a one-time thing which does have a bit of synergy with landfall, but still doesn't do much in this deck I feel like. If you want to be playing big monsters every turn, gush is usually a tempo loss, and is worse at bouncing lands to your hand than meloku or other repeatable effects. In short, I think gush doesn't provide as much card draw as guardian project, but if you really like the landfall synergy it provides, then keep it. I think it just depends on how much land bounce you want in this deck.

gingerthewritingdog. I think about cutting Risen Reef for Parcelbeast.

Both creatures aren't Sea-Cretures even though Risen Reef has a fitting name and artwork. But i noticed a lack of synergy because it only goes of with Zendikar's Roil as i counted only 3 other elementals. Parcelbeast could provide more value (Carddraw/Landfalltrigger). In the best case i can mutate it turn 2 onto Lotus Cobra or another smaller creature later. What do you think?

Parcelbeast is definitely faster and repeatable, which makes it arguably more powerful, but I have found that the Risen Reef + Zendikar's roil is pretty explosive and can get crazy with Ancient Greenwarden, so I really don't know on this one. It probably will just come down to which one you like more.

I'll give it a try as it is... Maybe i find a way to swap Parcelbeast in without cutting Risen Reef - would synergize just perfectly... Maybe i need to make a simic Elementals/Landfall theme...

Have you considered Ancient Animus or Pounce over Khalini Ambush? Or is Khalini Ambush there because it can be a land in a pinch? Also, if you can find a place for it, Eldritch Evolution would be pretty great card in this deck. It would go quite well with Chasm Skulker and Reef Worm.

I like cards with some kind of versatility... doesn‘s matter if it‘s adventure, „choose“-spells or the new MDFCs - therefore and to support the landfall theme i chose Khalni Ambush  ^Flip as i have some effects to bumb the land back to hand and cast it as removal if needed. I‘m aware of the fact that they are all 1 mana cheaper, therefore (and the little bonus effect in case of legendarys with no additional cost) i will list Ancient Animus to the maybeboard. Eldritch Evolution is a 1 mana morr one-time pod effect... with the upside of jumping 2cmc higher from your sacrificed target. Definitely worth to consider -> Maybeboard
