A couple of my Top 10 cards from The Lost Caverns of Ixalan have found a home in Boros Aggro. This deck takes the core of the Mono-White Humans deck and adds red to get powerful new cards Anim Pakal, Thousandth Moon and Inti, Seneschal of the Sun. Plus white creatures Kellan, Daring Traveler, and Warden of the Inner Sky into the deck. Each of these creatures adds value to the deck and gives it more overall power and consistency.
Anim Pakal is a token-generating engine. Any time you attack, Anim gets a +1/+1 counter and then creates a tapped and attacking colorless Gnome artifact creature token for each +1/+1 counter on her. Inti allows you to discard a card each time you attack. When you do a creature gets a +1/+1 counter and gains trample. Plus, whenever you discard a card, exile the top card of your library. You may play that card until your next end step. Inti synergies well with Anim Pakal because you can use Inti’s ability to add additional +1/+1 counters to Anim that will increase the number of Gnomes you create.
When Kellan attacks, you reveal the top card of your library. If it’s a creature card with mana value of 3 or less, put it into your hand. Otherwise, you may put it into your graveyard. All the creatures in the deck cost three mana or less, so you will get a second draw most of the time when Kellan attacks.
Finally, Warden of the Inner Sky can put a +1/+1 counter on herself by tapping three untapped artifacts and/or creatures. Then as long as Warden of the Inner Sky has three or more counters on it, it has flying and vigilance. This ability also synergies well with Inti’s ability.
Here’s a look at the full deck from SoIMBAGallade that finished 5th at the MGTO Challenge 64.
