Need a way for tokens to enter the battlefield with additional counters and other effects

[xenohedron]

Currently, the only affected card I know of is [[Littjara Mirrorlake]]. As currently implemented, the counter is added after the token enters the battlefield, but the token should enter the battlefield with the counter.

Littjara Mirrorlake - (Gatherer) (Scryfall) (EDHREC)

Land Littjara Mirrorlake enters the battlefield tapped. {T}: Add {U}. {2}{G}{G}{U}, {T}, Sacrifice Littjara Mirrorlake: Create a token that's a copy of target creature you control, except it enters the battlefield with an additional +1/+1 counter on it. Activate only as a sorcery.

[[Ochre Jelly]] is also affected

Ochre Jelly - (Gatherer) (Scryfall) (EDHREC)

{X}{G} Creature — Ooze 0/0 Trample Ochre Jelly enters the battlefield with X +1/+1 counters on it. Split — When Ochre Jelly dies, if it had two or more +1/+1 counters on it, create a token that's a copy of it at the beginning of the next end step. The token enters the battlefield with half that many +1/+1 counters on it, rounded down.

Tokens has etb feature, so etb ability with counters must works too.

[xenohedron]

I'm not sure what you mean, or practically how one can get the new token uuid in time to add counters to it before it enters

[JayDi85]

Etb counters uses special logic to add counters before go to battlefield

Like that:

token = new OozeTrampleToken token.addAbility(new etb(new countersEffect)) Effect effect = new CreateTokenEffect(token, x)

Encountering an issue with this approach @JayDi85 but will commit and outline in #11865

[JayDi85]

• [[Littjara Mirrorlake]] - “except it” - must use etb source effect with counters;
• [[Ochre Jelly]], [[Printlifter Ooze]] - “ token enters the battlefield with” - must put counters by token effect, not ability, see #11865

Printlifter Ooze - (Gatherer) (Scryfall) (EDHREC)

{1}{G} Creature — Ooze 2/2 Deathtouch Whenever Printlifter Ooze or another creature you control is turned face up, create a 0/0 green Ooze creature token with trample. The token enters the battlefield with X +1/+1 counters on it, where X is the number of other creatures you control. Disguise {3}{G}

Another examples:

• good: Magecraft - [[Deekah, Fractal Theorist]] -- add counters to all created tokens;
• good: sacrifice at the end - [[Dorothea's Retribution]] -- add effect to all created tokens;
• possible problem: Incubator effect - [[Eyes of Gitaxias]] -- add counters to all created tokens, but must add only to original incubator token only?
• bad: multiple effects and PT change - [[Gemini Engine]] - "add" dynamic PT to gemini token only, but set attacking status and add counters to all created tokens;

There are many potential problems. How to find:

1. Open TokenImpl.java and search usage of the putOntoBattlefield methods;
2. If card/effect do something with a created tokens then it can be potentially bugged:

• Good, nothing to check:
• Bad, can be bugged -- look at ability text (is it need modification for all tokens or for original only):

4. Repeat 1 for each putOntoBattlefield version.
