Modern Horizons 3: Playbooster pack contents and pull rates

With each Magic: The Gathering set, card slots of Playbooster packs change slightly. Here is what you can expect from the Modern Horizon 3 booster packs and the pull rate percentages. 

What is in MTG Modern Horizon 3 Playbooster packs?

Playable in Draft and Sealed, MH3 Magic: the Gathering Playbooster packs have a slot for new to Modern cards that were previously Eternal, or Commander cards only. A Wildcard slot was included that can include any rarity card with a treatment like Retro Frame, Borderless Frame Break, and even a Snow-Covered Waste basic land. 

Special Guest cards can show up within a Common rarity slot. The eight Commander MH3 cards may appear in the Wildcard slot and are likely not playable within Draft and Sealed games. Here is what a Modern Horizons 3 Playbooster may contain, according to WotC.
