I dunno, as a native-English speaker of (bad) Czech which has similar-ish thing to what you listed I am not sure these are such a mindfuck after all. If you threw all that at person at once they’d definitely lose their mind, but realistically they’ll learn it in something like this order (edit: updated to use similar example “hrát” - to play):

- conjugating verbs, “hraju” = I play, “hraje” = he/she plays

- past tense of verbs, “hrál jsem” = I was playing, “hrál” = he was playing, “hrála” = she was playing

- that verbs have a “perfective” form, so “zahraju” = I will play, “zahraje” = he/she will play

- naturally the past tense of these follow, “zahrál jsem” = I played, “zahrál” = he played, “zahrála” = she played

- that this can be conditional, “zahrál bych” = I would play, “zahrál by” = he would play, “zahrála by” = she would play

It’s not a stroll in the park, but the path that leads you to constructing those little sentence fragments isn’t too bad IMO. There are other complications tho (I just showed first and 2nd person singular, no plurals, I didn’t decline any nouns or adjectives, didn’t cover positions of words in a more complex sentence)
