A variety of cards, including Olivia, Opulent Outlaw , Misfortune Teller , and Life Insurance will generate a fair pile of Treasure tokens, while others like Captain Lannery Storm and Vihaan, Goldwaker give you something to do with them aside from generate mana
Then, creatures with -1/-1 counters on them cant block
My one reservation about Sceptre of Eternal Glory is that in more traditional environments its most likely just to be played in blue or green decks, which already have a way of leaning towards mana and stuff decks anyway
If a land was destroyed this way, its controller may search their library for up to two basic land cards, put them onto the battlefield tapped, then shuffle
It gives +1/+1 and haste to a creature, and creates a monk token to attach it to when you cast your second spell each turn
