It happens a lot more than you think, but yeah clodsire is definetely not the best matchup for keldeo, but it is still winnable. You just need to position it correctly and keep keldeo at decently good health. I find that players are extremely scared by keldeo and just end up using toxic to not let in pelliper to get a free u-turn off. Plus, if you combine it with arch, which also is countered by clod, you can overwhelm it.extremely questionable scenario since if you tera steel, clodsire now 2hkos you with earthquake. and if you come in on blisseys twave or seismic toss its also tilts the matchup. i always run some defense on clod for this and psyshock, and id just spam earthquake into it
