You pay 1 extra mana for your Glorious Anthem to get some protection against counterspells and instant speed removal, and the opportunity to pay 5 mana to get another strong effect for ending the game. Another benefit is that you can divide the white mana requirement over two turns, and that you can play it in Lurrus decks. Of course, it sucks if your opponent kills it after you level it to max level, before you get to attack, but they do have to pay 1 more mana to do it.
In aggressive decks, this is really good against control, because it makes counterspells much much worse, and lets you spend more mana without overextending to a wrath. Like other anthems it is good in aggro mirrors, as it makes your creatures larger than theirs, while midrange decks will struggle to deal with massive double striking creatures in the late game. With this on max level, attacking with, say, a Flickerwisp and two random tokens deals 12 damage in the air!
It is also good in dedicated token decks, as they like anthems in general and are more likely to be able to pay the initial 1-mana cost without disturbing their curve. They also regularly hit 5 lands, and the 5-cost effect is very scary in a token deck!

Overall I like this more than Glorious Anthem, but it's been a long time since I cut that card. I do run Force of Virtue and Dictate of Heliod, and I think I'll test this over Dictate.
