C Common Moon Magician X LIGHT Level 4 [ SpellcasterEffect ] ATK 1800 DEF 1500 If your opponent controls an Xyz Monster, you can Special Summon this card (from your hand)
If this card is sent to the GY as material for the Link Summon of a WATER monster: You can send cards from the top of your Deck to the GY, equal to the number of "Marincess" monsters you control, then, if a "Marincess" card(s) was sent to the GY by this effect, inflict 200 damage to your opponent for each "Marincess" card sent
To be clear, though, the two are very different cards and the main (only) resemblance is the mana cost and power and toughness, but even still Im a believer in Walking Ballista
Mickey Mouse - Brave Little Tailor If you're trying to play a solitary game where you put down cards and turn them sideways to win Mickey Mouse - Brave Little Tailor is the way to go
