cards rotating out of standard mtg Three-Year Rotation is Standard's Real Problem MTG Standard Rotation 2025: Overview

New cards arent all Bloomburrow has to offer, however

It helps that its fun to play, too

If the card has X in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost

The downside is that the lands now enter the battlefield tapped so you don't get to use them immediately and Roiling Regrowth is worse to copy than Harrow, since Reverberate'ing Harrow nets you 2 extra lands while copying Roiling Regrowth only nets you 1 extra land

You don't have to reveal the cards in the face-down pile, no matter which zone they're put into

Most characters that are played cant take any actions on the first turn they get played
