The Goblin Warlock can only be summoned when a creature dies, via its Tragic Backstory ability naturally
That, combined with STAB and a fantastic Ability that helped a grass Pokemon climb high on the grass list, is why it is here
As someone who doesnt play much D&D , I can be mostly indifferent to people thinking The Tarrasque is underpowered
Like the other Glimmer creatures in this set, Enduring Tenacity returns as an enchantment after it dies, turning into an enchantment while keeping the ability which is more valuable than its power or toughness
The set is highlighted by #4 Charizard Holographic, which is arguably the most important and recognizable Pokemon card in existance
Part of the trouble is that nobody knows for sure how rare it issome small percentage of Miku Secret Lair drops contain a copy of this card (or its Rainbow Foil version) as a random bonus to go along with the other cards in the box
