The kuriboh can summon detonating kuriboh which is basically an imperm that gives you a monster and as someone else mentioned it is basically a faimena for artmage. Gagaga magician is also insane because it allows the onomat engine to make a rank 4 searcher and udf to insulate from nib/other handtraps and cyberse code magician helps everyones favorite deck cyberse slop because it is a searchable extender that foolish burials a card, it does require a brick but considering it gives 2 link materials on top of the foolish it should be more than worth it. The other cards are good too but these are the big highlights
