You must follow the normal timing permissions and restrictions of the cards you play from your library
The first card that I got to illustrate was Ursula Deceiver in the Into the Inklands set that came out in March 2024
Golbez, Crystal Collector Rating: 4/10 Golbez is a classic Final Fantasy villain, yet the card is so out of place in this set
The Harbinger should, obviously, only be played in mono-blue Merfolk decks, and preferably in control shells that focus on icing out the opponent from doing much of anything rather than overwhelming them with tons of creatures, just like Richard Garfield intended
The cards officially revealed by ink type are: Mickey Mouse, Friendly Face (Amber) Zero to Hero (Amber) The Queen, Commanding Presence (Amber) Merlin, Shapeshifter (Amethyst) Winnie the Pooh, Hunny Wizard (Amethyst) The Sorcerer's Spellbook (Amethyst) I'm Stuck
This is especailly important now, as the MSRP for this set is significantly higher than it is for normal MTG sets
