Takenuma Plane: Kamigawa Whenever a creature leaves the battlefield, its controller draws a card
Especially if you happen to get Sylvia Brightspear and Reflections of Littjara out naming dragons
Basically, for each MTG color, you check if you have a dragon of that color and if you do you can put a counter on it
You can set it at one to shut off cheap spells like Lightning Bolt, Thoughtseize, or even Ragavan and hit many Modern decks hard
All the data and the images of the cards and expansions are taken from Scryfall and are the property of Wizards of the Coast (and / or their artist, for very old sets)
Legendary creatures have a whole set of rules that apply to them, but for the purposes of this article, all you need to know is that a legendary creature has the Legendary Creature text on it, like [c]Kenrith, the Returned King[/c] below
