Card of the Day - Shapesharer
While shapesharer can’t be used to copy “enter the battlefield” effects, it has plenty of other advantages over clone. Being able to change to a different creature every turn lets you take advantage of better creatures entering the battlefield. It also lets you take out legendary creatures that enter the battlefield after you’ve already played shapesharer. Being able to use other shapeshifters in this way is handy too. Finally, the fact that shapesharer is a changeling means that it’ll play nicely in tribal decks, letting you tutor it up with cards like Vedalken Aethermage.
