Here's yet another tribal build I have been working on, this time bringing on rampage from Ixla-Sorna! With this deck, I tried to make the dinos the main focus, but added a few more supporting cards. Here is a run through of the deck:
Mana and Efficient casting:
As far as the mana base goes there are three Cavern of Souls in the deck to make sure dinos can't be countered, and three Fabled Passages to thin the deck a bit. There are three creature cards that also help with casting, being Kinjalli's Caller to lower cost, Ilysian Caryatid as a druid, and Wayward Swordtooth providing an additional card draw; Swordtooth is also the easiest of the dinos to cast, and can trigger Caryatid's ability to gain access to more mana early on in the game. Descendants' Path allows for a pseudo draw that can potentially result in a large dino being casted for free while The Great Henge can easily be casted by having dinos out and be used as a pseudo land that gives a bit of life, a +1/+1 on a creature casted, and a card draw.
Dinos:
The easiest threat to cast is Shifting Ceratops with 5 power, protection from blue, and a versatile and easily activated ability. Trapjaw Tyrant is next with a conditional removal effect to make up for the lack of removal in this deck, and Carnage Tyrant is a well protected beater with Trample. Ghalta, Primal Hunger should be fairly easy to cast since most of the dinos in the deck are 5+ in power and there are various resources dedicated to mana and cost reduction. The last two are a bit tricky to cast, but are mainly meant as late game bombs; the first is Gishath, Sun's Avatar which can help drag more dinos on the field, and the second is Zacama, Primal Calamity with its various activated abilities that can be used.
Supporting cards:
To finish off the deck, there are a few cards here to help where giant creatures on the field alone will not do. In order by mana cost: Mayael's Aria grants a solid upkeep effect that gradually gets better, providing +1/+1 counters, 10 life, and/or a win con, so long as you have one of the dinos out on the field; Vivien, Arkbow Ranger has a decent +1 effect, but she is mainly included for her -3 that provides a form of removal, though her ultimate can prove useful by using some of the creatures in the sideboard; and finally, the dino loving planeswalker Huatli, Warrior Poet can help gain some life to keep afloat and provide 3/3 dino tokens, and an ultimate that can freeze opponent's creatures during combat or be a potential board wipe.
Though the deck lacks burn and removal through spells, I think it can hold its own. As always, I'm open to any feedback that could make the deck run smoother and more competitively as well as sideboard assistance.
