This deck has a fair share of basic lands because there are lots of repeatable ramp effects that search for basics, like Sakura-Tribe Elder
The need to be pitching blue spells to make it work is real, but there are enough blue decks in the format and enough combos that need to be stopped on your opponents turn that this card is likely to see constant play for years, even if mostly out of the sideboard
The other is Hawlucha
The majority of these arent better than a generically good cEDH card in the list, such as a counterspell, but they are good to keep in mind when brewing
You get to draw an extra card, re-spend all your mana, and get an extra combat stepnot to mention extra upkeep/end step triggers, planeswalker activations, and so on
