mew first edition pokemon card - Promo #8 From the Wizards Black Star Promos set Mew 016/036 CP5 1st Edition

Its power and toughness are equal to the number of Islands you control

Amass is the perfect keyword to bring back for a set about large battles, and can help to visualize the growing strength and larger armies without the need for masses of tokens

You dont need to rely on external pieces for card draw in a Tannuk deck, mind you

If the creature an opponent controls is an illegal target as the ability resolves, nothing happens and the creature you control remains as it was

You cant change the distribution you announced when you activated the ability

It does nothing on its own until a cards text cares about how many are present or requires you to add/remove them
