I love a good Astral Slide and Lightning Rift deck, but the plan is too reliant on mediocre cards that other decks wouldn't want to take. If this wasn't limited to 2003 as the cutoff of card printings, I'd gladly add in some of the powerful 1-mana cyclers out of Ikoria, but unfortunately for the strategy as it stands it isn't staying.

A handful of cards with cycling will be sticking around, simply because they're still good cards.
