mtg cards that let you take extra turns In general how good are allow to a an turn ? TIA 😊 Why is it so common

Invasion of Mercadia C-Tier: Basically the battle version of Bitter Reunion, except the ability to give all of your creatures haste is likely more of an upside than potentially flipping into a 3/3, which means this is probably just a worse version of a card that already exists

Academy, when in a format with Mox etc, is easily one of the most powerful cards of all time, like top 5 above all the other lands and most of the power

The first is +2 and lets you sacrifice a dork to search up a creature with a +1 mana value and slam it onto your battlefield - nice growing over time like a Birthing Pod
