The sins of Green Baboon, Defender of the Forest

Throughout the guide, whenever we talked about the Fire Kings' effects to Special Summon themselves from the hand, we blamed "the Green Baboon ruling" for the reason we can only Special Summon 1 monster, even if we have multiple monsters with the same effect in the hand.

What's up with that?

	Green Baboon, Defender of the Forest Level 7 EARTH Beast When a face-up Beast monster you control is destroyed and sent to the GY, while this card is in your hand or GY (except during the Damage Step): You can pay 1000 LP; Special Summon this card. ATK 2600 | DEF 1800

This card is what's up. It was very powerful in the OCG in 2006, causing it to be Limited on its release in the TCG in 2007, and staying that way until 2009.

As a consequence, we now have the following ruling:

Only one Trigger Effect that Special Summons the activating monster itself, and that can be activated in the hand, can be activated in any given Chain. A "Trigger Effect that Special Summons the monster itself, and can be activated in the hand" also includes effects that can be activated in either the hand or the Graveyard.

Regardless of whether the effect is actually being activated in the hand or Graveyard, only one of this kind of Trigger Effect can be activated on any given Chain.

All our Fire King cards that can Special Summon themselves from the hand are affected by this ruling. Thus, we are not able to activate Legendary Fire King Ponix from the hand and Sacred Fire King Garunix from the hand or GY in the same Chain, for example.

Make sure to always keep this ruling in mind as you perform your combos.
