- "The Tricky" is not a Special Summon monster. Despite being a monster that can be Normal Summoned, it is a monster that can also be Special Summoned by performing the procedure of discarding 1 card from the hand. In other words, Special Summoning "The Tricky" from the hand by discarding 1 card from the hand does not start a Chain, and is not an effect that activates. Therefore, even if "Goblin of Greed" is applying its effect that prevents effects from being activated by discarding cards, "The Tricky" can be Special Summoned by the method described in its text.
