Click the hyperlink button. Then the url tags should appear. After the first url type the equals sign = followed by the actual url. In between the url tags, type the name of the card or whatever you want the hyperlink to say. Ex. -
Cackling CounterpartDimir Doppleganger is solid since it also doubles as graveyard removal.
Rite of Replication is too good to cut just based on the fact that you can copy a Djinn of Wishes. Seriously though, copying any random, non-Legendary fatty is quite strong.
Vesuvan Shapeshifter is still in the stack too. We have quite a few morph creatures though and the surprise factor is a nice bonus. We've either cut or never included the other cards you listed.
I hope this helps.
