Earlier today, Mark Rosewater or popularly known as Maro posted on his Tumblr account some of the hints and easter eggs of the upcoming Magic: the Gathering set Ikoria: Lair of the Behemoths. He did a Maro Teaser on what cards and creature types to expect aside from the given info of having big and monstrous creatures in the set.
To quote his post,
The following can be found in Ikoria:
• Magic’s seventh Egg
• A card with the text “four or more times this game”
• A card with the text “total power 10 or less”
• Magic’s largest power/toughness granting aura.
• A card with the text “X is the number of times this creature has mutated”
• Magic’s third and fourth card with “(Zero is even.)” reminder text.
• Three cards with the text “different name(s)”
• Thirteen different types of counters
• A card that says “choose a kind of counter at random”
• A card with the text “remove eight foreshadow counters”
• And a cycle that players have been asking us to make for over ten years
In addition, Ikoria has creatures with the following creature types:
• Dinosaur Turtle
• Shark Beast
• Demon Kraken
• Elemental Otter
• Brushwagg
• Hellion Horror
• and a Nightmare Squirrel (Yes, a Squirrel in a Standard-legal set!)
