A fully gray row is rarer with SLANT: it happens 13.8% of the time, against 16.1% for CLAST.

CLAST is not on the possible-answer list, so it cannot solve the game on turn one here. It can still be a useful guess.

How these two openers fit together

CLAST and SLANT share 4 of their 5 letters (A, L, S, T), so as a pair they only cover 6 distinct letters. Treat them as alternatives rather than partners, because playing both wastes most of the second guess.

Played back to back, CLAST then SLANT earns 6.38 bits of information in total, 0.89 bits more than the better word manages alone.
