For example, Tatyova, Steward of Tides has the ability Whenever a land enters the battlefield under your control, if you control seven or more lands, [effect]. If you choose that ability, it will go on the stack regardless of how many lands you control
It doesn't tap, so you can use it if you have four extra mana
Thanks to the slower nature of Commander, you should have ample time to set the combo up, as well, but it will have a smaller impact on the game thanks to having four opponents
Terra, Magical Adept - I did a check in my own cube for enchantments (I dont really care about enchantments as a theme in my own cube, which I discussed in the Duskmourn article) but when I did a check, there looked to be enough of a critical mass to make this work without a lot of effort, which is usually a fine barometer for how the card works out in generic cube decks: Being a 4/2 for 3 could also be a fine fail case, although that isnt that amazing by 2025 creature standards either
