Venat, Heart of Hydaelyn / Hydaelyn, the Mothercrystal In commander the name of the game is legendary spells, so planeswalkers and cards you already want in your white deck like Flowering of the White Tree and Caduceus, Staff of Hermes, get much better with Venat, Heart of Hydaelyn in play
It works well in decks dedicated to ramp with cards like Reshape the Earth, but its rather inefficient otherwise
In short: Alternative costs are a different price tag, but in general with the same timing rules unless the card or keyword explicitly says otherwise
Players can have contrasting energy types together, allowing them to easily switch between Pokmon depending on what their opponent has: Active and Benched
