Greetings everyone!
I created this deck for my girlfriend, who already owns an RG (Gruul) aggro deck, and got a Chandra, Acolyte of Flame and a Creeping Trailblazer from a booster-pack on Christmas. She liked Chandra's artwork, so my mission became clear: Build a deck, that incorporates both of these cards and is not too difficult to handle.
I came up with this deck, which plays around Bloodbriar and Overgrowth Elemental.
They synergize well with Chandra, Acolyte of Flame 's elementals, that get sacrificed at the end of turn. And so do all elementals that get sacrificed (!!!BUT NOT EXILED!!!) at the end of the turn, so here come the beatdown squad: Spark Elemental, Hellspark Elemental, and Ball Lightning. These will be reckless, relentless, and ruthless in damaging the enemy, while also granting +1/+1 counters to Bloodbriar and Overgrowth Elemental.
Because obviously many creature cards will end up in our graveyard - and thanks to Barbarian_Sun_Pope's suggestion, I added Thunderkin Awakener, which enables us to recycle all the nice suicide creatures again and again.
There is a negative though: This whole strategy will burn through your hand faster than thermite through your playing table! To fix that I added a variety of spells, that will hopefully provide enough card-draw:
Hunter's Insight (instant speed -> cast on creature that was not blocked)
Life's Legacy (Your creature dies anyways at the end of the turn? Get some cards as a bonus!)
Elemental Bond (Turns each suicide creature into card-draw)
To maximize the value of Chandra, Acolyte of Flame, I added a few red planeswalkers, which synergize well with the deck, while being easy on the money:
Chandra, Novice Pyromancer
Domri, Anarch of Bolas
Samut, the Tested
Last but not least, Creeping Trailblazer provides general support for all of your elementals by making them stronger just by being on the battlefield.
tl;dr
Give Overgrowth Elemental or Bloodbriar +1/+1 counters, by playing elementals, that get sacrificed at the end of turn (e.g. Spark Elemental).
Thunderkin Awakener and card-draw mechanics (e.g. Hunter's Insight let you recycle your elementals.
Some planeswalkers (e.g. Chandra, Acolyte of Flame) seal the deal.
Creeping Trailblazer makes your creatures stronger.
If you like the deck, or have an idea on how to improve it, please leave a comment!
Thank you very much and have fun playing! MTG IS AWESOME!
