No, they don't die. State-based actions are only checked in between resolving things on the stack. (More precisely, they're checked right before a player receives priority.) They are not checked mid-resolution of a spell/ability.

Imagine state-based actions as a guard who checks on the game state. The thing is, they only look at the game state at specific points in time - in between those specific points, anything can happen that would normally be taken care of by state-based actions (e.g. a player being at 0 life) and the guard won't notice (nor care).

At the time just before Thassa's triggered flicker begins to resolve, state-based actions will have been checked. The elementals (I assume) have at least 1 toughness, so they won't be put into the graveyard as a state-based action. Then the flicker starts resolving, and during this time, the state-based action "guard" isn't looking at the game state until the flicker finishes resolving.

By the time the "guard" looks back at the game state post-flicker (resolution of the ability), Master of Waves ' static buff is in effect, and the previously created elementals have at least 1 toughness again, so the "guard" doesn't move them to the graveyard, being none the wiser about the elementals "temporarily" having had 0 toughness.

If the Heliod card is used to flicker Master of Waves do any Elementals already on the field die?

Can you please do a very clear explanation, as this question has been popping up a lot?

I thought that as well, but apparently state based actions aren't checked until Master of Waves is back on the field.

Quite a few judges confirmed this in the Facebook Pioneer group.

From the FB topic:

"State based actions are not checked until the ability finishes resolving. So there is never a time to kill them before Master of Waves is back on the field, and his trigger goes on the stack to make more Elementals.

Also, to the individual who suggested the new Thassa and Master of Waves synergy, it is actually a “non-bo”. The original tokens you’d get would die by the state based effect of Master leaving the battlefield. Unless you had 2 Masters in play.

And with Kozilek's Return being played, it gets around the whole “pro-red” thing.

It seems that after the last bans Control is becoming very dominant.

Izzet Phoenix is still strong. It has probably been the most consistent deck that hasn't been effected by bans.

Mono black Aggro decks are also still doing well.

A new deck doing the rounds is mono blue Tempo, and that has a new tool in its belt after Theros Beyond Death is released. The new Thassa god will be able to flicker Master of Waves once a turn FOR NO COST.

There has been a lot of talk lately about an infinite combo which will become viable once Theros Beyond Death drops.

In case you haven't heard of it, it combines the new Heliod god with Walking Ballista

The Ballista must start with two +1/+1 counters on it.

Give it Lifelink with Heliod, then remove a counter to deal damage to your opponent, which will add a counter, remove that counter to deal damage, which will add a counter ad infinitum.

People think that Wizards may ban Walking Ballista if the combo becomes too popular.

My guess is that it will, due to the popularity of the former Felidar Guardian / Saheeli Rai infinite combo in Pioneer, which saw Felidar Guardian banned.

If you have any thoughts on the current or upcoming meta, feel free to share them.

DeinoStinkus: Only saw your comment just now. Seems like there's no subscribe buttons for custom cards? Oh well.

Anyway, I don't like Fear since it's swingy and obsoleted. The last ability is indeed way powerful even if I mostly made this with EDH with mind. It needs to stay in some form though, since pumping is the tribal signature of Shades, and this was in part an attempt at a Shades tribal card. I could easily see increasing the cost to something like 2-3 mana, possibly with no generic costs either since devotion already incentives mono-black. The protection could also easily be cut to facilitate interaction; it's just there to reference Master of Waves as much as possible.

I think that you can cut Healer of the Glade to add something that gives devotion to blue. There are some suggestions:
