Thank you for the Link to Alex’s Anki deck! It looks like a good collection for sentence mining.
I found LTL’s own blog on basic Chinese grammar 
Basic Chinese Grammar // A Simple Guide To Grammar (With Quiz) (ltl-xian.com). I might recommend drilling sentences and reviewing the basic rules. A little theory and a lot of practice go a long way.
I also like some of the resources on AllSet’s Chinese Grammar Wiki. Here is the page on basic grammar. Sentence Patterns - Chinese Grammar Wiki (allsetlearning.com). The charts show to build sentences using different elements of Chinese grammar. However, there is no pinyin, so if you do not recognize the characters it will take longer to work through the examples.
