Amulet of Ambition

Since Paleozoic Hallucigenia, as a monster, is summoned at such a low level, Amulet of Ambition is a great card to use for a powerful attack boost.


Here are some other Paleozoic monsters you could use as they are all able to trigger each other's special summon effect. Paleozoic Pikaia and Paleozoic Marella is a great way to send Your Paleozoic monsters to the graveyard. Paleozoic Leanchiolia can return banish Paleozoics to your graveyard.

Half shut is better. If can protect your monster from destroyed by battle when ramming higher attack monster, and you can chain it to wod.

not necessarily, floodgate can only be used during normal summon. where as Canada can be used during any phase

I agree. Although floodgate is more powerful, canadia is more versatile. With floodgate, you must use it during an opponent's summon which occasionally your opponent might actually do that intentionally to bait your floodgate.
Brutal, really cool in wetland decks
This card is buggy, the effects doesn't activate properly some of the time as my opponent uses it on me and my monsters don't lose half their attack, when i do it, they don't lose half either, neither of us had effects that countered it, Konami needs to get it to work!
I was got this... But when? Ah a weekly pack? I guess
