Yu-Gi-Oh! IMPH reportedly adds two Atlantis cards that become Umi
IMPH-JP019 Rampant Wings of Atlantis and IMPH-JP049 Codaedalus, both WATER Sea Serpents, reportedly turn into "Umi" on the field. Japan only so far.

Two Japanese cards from IMPH have reportedly been revealed with effects tied to "Atlantis, City of the Sea Dragon": IMPH-JP019 Rampant Wings of Atlantis and IMPH-JP049 Codaedalus. Both are WATER Sea Serpents, and both reportedly take on the name "Umi" while they sit on the field.
The reveals are for the Japanese (OCG) product. No release date, price, or English-language release has been announced.
Rampant Wings of Atlantis (IMPH-JP019)
Rampant Wings of Atlantis (romanised Atlantis no Bouyoku) is reportedly a Level 5 WATER Sea Serpent Effect Monster with 2000 ATK and 2400 DEF.
Its first effect lets you send it from your hand to the GY along with 1 Spell/Trap or "Umi" from your hand or face-up field. You then target 1 card your opponent controls and send it to the GY.
The second effect is the name change: while the card is on the field, it becomes "Umi".
The third effect works from the graveyard. If you control "Atlantis, City of the Sea Dragon", you can banish this card from your GY to Special Summon 1 Level 4 or lower Sea Serpent monster from your hand or Deck. Effects (1) and (3) are each limited to once per turn, counted by card name.
Codaedalus (IMPH-JP049)
Codaedalus is reportedly a WATER Sea Serpent Link/Effect Monster with 1400 ATK and LINK-2. Its link arrows are listed as "B R", and its Link Materials are 2 WATER monsters. It can only be Special Summoned once per turn by card name.
If Codaedalus is Link Summoned, you can activate its first effect. During the End Phase of that turn, you add to your hand 1 card from your GY that mentions "Atlantis, City of the Sea Dragon". The exclusion is listed as "Codaelus", a spelling that differs from the card's own name.
Like its counterpart, Codaedalus becomes "Umi" while on the field. Its third effect, usable once per turn, lets you send 1 face-up "Umi" you control to the GY to send up to 2 Spells/Traps on the field to the GY.
Why it matters
The two cards approach the same theme from different angles. Rampant Wings of Atlantis removes an opposing card and Special Summons a Level 4 or lower Sea Serpent, while Codaedalus retrieves Atlantis-related cards and clears Spells/Traps. Both are also reported to count as "Umi" on the field.
IMPH has also been the subject of other reveals. TCGKing previously reported ten Japanese cards for the set that reportedly mix Amazoness and Harpie Lady cards into a Mai Valentine strategy. These two Atlantis cards add a separate WATER Sea Serpent thread to the same set.
What it means for players
- Sea Serpent and Atlantis players can note that both cards reportedly use the "Umi" name on the field.
- Rampant Wings of Atlantis is the only one of the two that starts from the hand, and its Special Summon effect is reported to require "Atlantis, City of the Sea Dragon" to be under your control.
- Codaedalus needs 2 WATER monsters as materials, so it fits a WATER-based build.
- The reveals are Japanese-language cards. No English release has been announced.
What is still unknown
The release date of the product containing IMPH-JP019 and IMPH-JP049 is not announced yet, and neither are its price and format. The rarities of the two cards are not stated. The link arrow directions of Codaedalus are available only as "B R". Whether and when English-language versions will be released is also not announced yet.
