Weird Interactions with Yarok the Desecrated as Commander

[TanukiRuby]

So I have a Yarok the Desecrated commander deck, and some of the ways that this impacts Enter the Battlefield stuff gets super weird. Ichormoon Gauntlet is so very strong in this deck, and creates a truly stupidly amazing effect even without going for Superfriend tactics, since it adds two counters on every non creature ETB. Invasion of Zendikar generates four Landfall triggers. Threefold Thunderhulk with Yarok the Descrated onboard is 6/6 with 6 Gnome Tokens. Amass Zombies/Orcs on ETB creates a fairly large Army token pretty quickly. Are there any other interactions with this doubling effect that are not obvious?

That interaction does not work the way you think it does. Ichormoon Gauntlet only adds counters when you cast a noncreature spell, not when permanents enter the battlefield. However, Displacer Kitten is another strong pick for Yarok because it can blink something any time you cast a noncreature spell.

Threefold Thunderhulk with Yarok the Descrated onboard is 6/6 with 6 Gnome Tokens.

It enters with the counters, it doesn't get them on ETB, so it is still a 3/3 on entry. That said, it will get 6 1/1 Gnomes on entry.

Thank you for the clarifications on these, as the way I read Ichormoon Gauntlet (on casting) is not equivalent to ETB, but might be misconstrued with artifacts and enchantments. yet can still payoff with any non-creature spell cast, including instants, battles, et al. Threefold Thunderhulk does not interact with Yarok the Desecrated the same way Doubling Season would, if I understand this -- then again, few things do work that way. But in this case, how does Yarok the Desecrated work with Doubling Season -- tripling or quadrupling? As despite the cost, it becomes very tempting.

At least Invasion of Zendikar still causes the Scute Swarm explosion. As four lands entering goes ham, right? And the static ability of Kaito Dancing Shadow works very, very well with the commander.

. But in this case, how does Yarok the Desecrated work with Doubling Season -- tripling or quadrupling? As despite the cost, it becomes very tempting.

For that you do need to make sure you have an ETB counters application not an "enters with" counters. For example, Hydra's Growth. Under normal circumstances this is a single +1/+1 counter being added, Yarok will make it two instances of a single +1/+1 counter being added for two +1/+1 counters total if both the original trigger and its copy resolve, Doubling Season will instead make each instance of getting one +1/+1 counter into getting two of them for a total of four of them, but again both triggers would have to resolve.

Yarok and Doubling Season are fundamentally different effects that don't interact with each other at all.

Yarok says that if an ETB trigger triggers, it triggers twice. This means anything that says "When <this thing> enters the battlefield," or "Whenever a <whatever> enters the battlefield" gets doubled. So yes, Invasion of Zendikar now gets you two lands twice, for four lands. If you have a Landfall card out, that gets doubled too, so you actually get eight triggers.

Doubling Season is a replacement effect. If you would create tokens, though any means, you create twice as many instead. If you would put counters on something, through any means, you put twice as many instead.

Now, if an ETB trigger creates tokens or puts counters, then it will get doubled up by Yarok and by Doubling Season. Just, for different reasons.

Mostly, Yarok is just "ETB? Double it"... that's not super interesting. Whether that's Ravenous Chupacabra, Mulldrifter, Reclamation Sage, Omen of the Dead, whatever, we've seen this before. The one weird interaction I can think of is Isochron Scepter, because doubling that ETB means that you get two cards exiled, and the weirdness of Magic rules means that you get to cast both of them when you activate the stick. I actually built a whole deck around this; turns out that if you put a Mana Drain AND a Word of Command under a Sceptre, it makes people cry. Then again, just a regular Word of Command does that, because who's got the time to read all that text?

One weird interaction with Threefold Thunderhulk is that - if you get 2 ETB triggers - you can resolve one, then sac the newly made gnome tokens to pump Thunderhulk, which will then make more tokens based on its buffed power. It costs a ton of mana, though.

Btw, this is another difference between Yarok and Doubling Season. Yarok is like copying ETB abilities (each copy resolves independently). In contrast, season replaces an action with another ("make 3 tokens" becomes "make 6 tokens", but if you have effects that triggere whenever you make one or more tokens, they would only trigger once, bcs it's technically one action).
