Offense:
Knight of Grace: This card is definitely our strongest earlygame creature, as hexproof from black defends it against a multitude of spells that are specifically aimed at killing creatures like these.
Knight of Malice: This card is less likely to stick on the field than Knight of Grace, but its offensive capabilities are the same.
Danitha Capashen, Paragon: This card has a few things going for it. It has firststrike, which goes with our theme. It has lifelink, which plays especially well against red aggro, and it has vigilance, which makes attacking with it completely free. The downside is it is only a 2/2, so it can lose many more fights when compared to Knight of Grace or Knight of Malice, but if it does stick, it is probably stronger overall. One upside is that we can equip it with Blackblade Reforged!
Lyra Dawnbringer: This one is the most powerful creature we have. 5/5 is huge, flying makes it harder to block, first strike means that even if it is block it will rarely lose, and lifelink means that even if it does lose we still get something from it.
Kwende, Pride of Femeref: This card is the glue that sticks a lot of already powerful creatures together. Hes not particularly good on his own though, so never play him if there are no other first strikers on the field.
Blackblade Reforged: This sword is awesome! as long as you have a legendary creature on the field. Since half our creatures are legendary however, equiping this isnt the hardest task in the world. Double strike means we get double the damage. A Lyra Dawnbringer wielding this blade while Kwende, Pride of Femeref is in play hits for lethal.
Defense:
Knight of Autumn: We are starting off with this card since it can be quite good offensively as well. It can be a 4/3, it can give you life, or it can destroy an enchantment, which is its primary defensive purpose.
Status / Statue: Statue allows us to destroy a creature or enchantment, which is its primary defensive purpose, but what makes this stronger than many other options, is the fact that status on a firststriker kills whatever it is fighting, without dying, for just .
Conclave Tribunal: This card is really good at dealing with anything, and in a creature heavy deck, it can be incredibly cheap as well.
Kraul Harpooner: This little guy can kill bigger flyers. That is why it is here. He will die when he does this, but you are trading a cheap creature for an expensive one, which is a win! If there are no worth while flyers to target, there are better options on the sideboard.
Shalai, Voice of Plenty: Shalai is pure value in this deck. She protects us against so many things, and she isnt the easiest creature to deal with either. What sells this card though is the active ability. It is expensive, but gaining +1/+1 counters across the board is just too good to pass by. When it comes to first strikers, often times +1 attack means you can win fights 1 higher on the mana curve. When it comes to double-strike, often times it will play out as a +2 in terms of damage output, which puts your creatures on a whole different level.
Utility:
Flower / Flourish: Flower helps us with our early mana-fixing/land hits. by itself it wouldnt justify a spot in the deck, but it just so happens that we can use Flourish as well. Flourish gives our creatures +2/+2, which follows the same logic as the explanation with Shalai, Voice of Plenty. Flourish may play out as a +4 in terms of damage output across the board. It can finish out games. By itself i might be hesitant to add this one as well, but the two parts together means that this spell is always relevant.
Journey to Eternity
: This card is just cool. It protects a creature, and when it flips it allows us to bring all our dead creatures back from the graveyard. As long as you have Kwende, Pride of Femeref out on the field, most of our creatures are easily worth 5 mana.
