+1/+1 counters

[Tonygrabowski4]

How does  {Doubling Season} interact with cards that enter the battlefield with counters?

[Sparkle Ninja]

Doubles them as they enter the battlefield.
Good way to instantly ult a Planeswalker when it hits the field

[Tonygrabowski4]

So a card like  {Kalonian Hydra} would enter with eight counters?

[Sparkle Ninja]

Yes

[Prplprince]

So a card like  {Kalonian Hydra} would enter with eight counters?

And every time kalonian's ability hits that quadruple the counters. It's an edh fav of mine

Triple, actually.  Hydra's ability will basically say "I have 8 counters, so let's add 8.", then Doubling Season will be like "You want to add 8?  Have 16 instead.

Your right I used the wrong multiplyer :/

Actually that is incorrect, the abilities are put on the stack, hydra says double and doubling season says double, doesn't matter which resolves first, they will quadruple.

10/1/2005   If there are two Doubling Seasons on the battlefield, then the number of tokens or counters is four times the original number. If there are three on the battlefield, then the number of tokens or counters is eight times the original number, and so on.

Doubling season ruling pretty much says that.

The math ends up being strange due to the fact that the hydra is the source of the first addition.

If I have 4 +1/+1 counters on something, Hydra will try to add 4 counters due to its own effect, the doubling season will add twice as many, giving it 8 counters.

The {doubling season} itself does not double the amount of counters that are already on the creatures so it is tripling the amount of counters on each creature.

That is correct, I appologize.

The reason for that is because there are two doubling effects being applied to the same event.  With two Doubling Seasons on the board and an effect says "Place a +1/+1 counter", Doubling effect 1 says 'have 2!', then doubling effect 2 says 'you're placing 2? Have 4!'

In the original scenario, however, there's only the original event: "Place X counters, where X is the number already there" (Essentially what the hydra means), modified by the doubling effect: "Have 2X counters instead!"
