Hello, I am no modern specialist, yet when I look at the deck I have the impression unbalance between killing the opponent with Card Advantage and Big creatures on the one hand (I think you don't really need even half the "creatures" you have to get the opponent to death) and the control of the board and the tempo to get out all these big monsters. If you plan to take out a game in modern format by the way big monsters, I think you need to know that it is a very difficult plan to get out because many decks will either try (and often manage to proceed) kill you with a combo much more quickly, either by an aggressive plan which is often as quick. If you plan not to win by turn 4-6 lets' say without too much disruption, you have the control role to prevent the opponent from crushing you. You surely have life gain that can slow down (but don't be too optimistic) burn, some early blockers (I think not enough) against aggressive creatures. You need a plan to
disrupt combos,
path to exile as suggested is a good card since useful against aggressive and some combo plans. I think you need also mana acceleration, so that your big creatures can have more impact against these decks.
And then I think you need disruption to fight more permissive control decks.
To sum it up:
Reduce the numbers of big creatures, you d'ont need so much. Try to keep some that are good against control decks (
gaea's revenge is a good example)
Put some mana acceleration so that you can ramp up your big spells against quick decks.
Include some disruption against combos and permissive decks (you need to know what are the key cards to win against these decks and find a way to get them on the board).
Some mor thoughts:
If you include mor cheap spells,
eidolon of blossoms could be a great card isn'it?
Cheers up because it is an
uphill battle but it is good to try, because building your own deck and optimize it is a great way to become a skilled magic player!
Some cards I would think testing in this deck:
utopia sprawl,
sheltered aerie,
overgrowth,
mana bloom,
verdant haven,
frontier siege (either mana or fighting mode with your angels),
fertile ground,
trace of abundanceDovescape (some flying power with disruption/soft lock and you can get back your enchantments with
starfield of nyx)
