Id advise using it as part of the 99 and not as your commander, though
Even in an Un -set friendly game this has literal zero merit outside of maybe winning the game, and seems like more of a hassle to track than anything
You see it Standard, but also beginning to appear in Modern in Blue-based Control shells as its a win condition
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
Clearly, little dudes for 1B that always draw you cards are better than little dudes for 1B that sometimes draw you cards
Though, of course, if you have another ability you were counting on later in the game, you can bring them back to your hand and try again
