Discard 1 "Paleozoic" card, then draw 2 cards. Once per Chain, when a Trap Card is activated while this card is in your Graveyard: Special Summon this card as a Normal Monster (Aqua-Type/WATER/Level 2/ATK 1200/DEF 0). (This card is NOT treated as a Trap Card.) If Summoned this way, this card is unaffected by monster effects, also banish it when it leaves the field.
Since Paleozoic monsters are WATER attribute and below Level 3, you can use Wetlands to greatly increase their ATK power. Amulet of Ambition also further boosts their attacking power against higher level monsters.
Since Paleozoic monsters are of WATER attribute, they can contribute to the Summoning of Citadel Whale, while at the same time they can be banished using Sea Stealth Attack’s effects as well.
Endless Trap Inferno(skill) Can be used when you have 3 trap cards in the Graveyard. 1 random Trap Card in your Graveyard is added to your hand. Then, shuffle 1 random Trap Card in your Graveyard into your Deck. This skill can only be used once per Duel.
