Beginners will be better off starting with an entry-level account dont need to worry about the other options yet
So as far as strategy goes I would recommend using a spread damage type Pokemon like the Spiritomb card from this set paired with Giratina so almost every Pokemon you see would have damage on it
Craft with two that share a card type ( , Exile this artifact, Exile the two from among other permanents you control and/or cards from your graveyard: Return this card transformed under its owner's control
Power Double Vehicle - 4 mana with a Red included, 3/3 Menace, crew 1, when this deals combat damage to a player, double it
The unique creature from the deck, Imaryll, Elfhame Elite is a great way to sneak your damage through with that massive Elven army
While she costs one mana more than Blood Artist and Zulaport Cutthroat, doesnt gain you life, doesnt count tokens, and is legendary, thus prohibiting multiples, she does act as a lord for all your other creatures (including tokens)
