As I draft with bots, I keep reaching a point of "Oh... well now that I have these ~3-6 payoffs, I just take all the good cycling cards and I'm set, right?" This also often means falling into Jeskai, where most of the best obvious payoffs are. This is fun when it's rare, but not when it's every draft; it's also not interesting gameplay to just cycle to your payoffs then win or lose, glass-cannon style.
Removing Irencrag is step 1, but I think I need to take a harder look at some of the other "easy" payoffs. Astral Drift, for instance, is a great card but its engine at least requires specific drafting & deckbuilding skills. Hopefully aggro decks can get underneath them or can remove the key payoffs easily enough that "take all the cyclers" becomes not always correct, but that's hard to test without playing out the games.
