mcdonalds pokemon cards 1999 McDonald's Card, Toys & Collectibles, Fan Merchandise, Other Merchandise on Carousell McDonald's Collection (TCG) - Bulbapedia,

The final usual card here is Spellskite

I would suggest swapping it out with Ruthless Radrat

4 Svyelun Of Sea And Sky The God Of Merfolk The other contender for best mono-blue Merfolk kindred commander, Svyelun of Sea and Sky is a Merfolk God for three mana, offering both card advantage and protection to your Merfolk

If you have three Dark Charizards for example (lucky) youd only be allowed one more Dark Charizard

Unless you have a dedicated build for Fall of Gil-galadFall of Gil-galad, I say pass

If you are mostly in red, a Volcanic Island here and a Rakdos Signet there will set you up to take that third-pack Time Walk or Mind Twist with reasonable confidence that you can cast it
