Modern Horizons 2/Trivia

Maro's MH2 Teaser
Mark Rosewater gave his traditional teaser with the following hints.

First up, here are some things you can expect:

 * a legendary character best known for having his name on a powerful card (that’s been banned) finally gets a legendary creature
 * a theme on only a handful of cards in Modern Horizons gets a larger presence "mix-and-match" mechanics
 * a Frog twenty-six years in the making, a riff on Chub Toad which had Bushido before the mechanic was named.
 * new split cards
 * a Future Sight mechanic reused for the first time Wizardcycling
 * a character that first appeared in a Magic novel finally becomes a legendary creature
 * a card with the number words "four" and "fourteen"
 * a fan-favorite animal character finally becomes a legendary creature
 * a white enchantment with a trigger that investigates
 * a planeswalker from the past that has previously only had a legendary creature card

Here are some snippets from rules text that appear in the set:

 * “Whenever you cast your third spell each turn,”
 * “for each other Ooze you control.”
 * “If an ability of a  or another  you control triggers, that ability triggers an additional time.”  (Shaman, Wizard)
 * “This ability costs 1 less to activate for each +1/+1 counter on creatures you control.” Deepwood Denizen
 * “you may sacrifice a Mountain rather than pay this spell’s mana cost.” Mine Collapse
 * “Trample over planeswalkers” Thrasta, Tempest's Roar
 * “If an Insect card was milled this way,”
 * “Protection from permanents with corruption counters on them”
 * “choose a number between 1 and 5. Flip that many coins.” Yusri, Fortune's Flame
 * “instead create one of each.”

Here are some type lines from the set:

 * Artifact Creature – Assembly-Worker
 * Creature – Dinosaur Illusion Phantasmal Dreadmaw
 * Creature – Dauthi Rogue Dauthi Voidwalker
 * Creature – Skeleton Shaman
 * Creature – Elemental Incarnation Grief</c>, etc.
 * Artifact Creature – Clue Myr Parcel Myr</c>
 * Tribal Artifact – Lhurgoyf
 * Legendary Creature – Merfolk God Svyelun of Sea and Sky</c>
 * Legendary Creature – Snake Elf Scout Lonis, Cryptozoologist</c>
 * Legendary Creature – Squirrel Warrior

Finally, here are some of the mechanics in the set
(I replaced all the letters with X's.) Each listed keyword is a different non-evergreen keyword. No promise that it will appear in the set more than once, but some do appear in number. Spaces or punctuation didn't get X's. Note: the MH1 reprints don't count as they are not officially part of the MH2 (they are numbered separately).
