-Remove every creature your opponent puts down.
-Continually double collect with an untargettable divine collector, rendering all the opponents removal and de-buffs dead for the whole match.
-Kill the enemy god with Kaios or multiple chip damage.
Mulligan for Divine Guardian to start collecting as soon as possible. Firebomb is also a good keep for clearing enemy collectors.
With lands the aim is to build from the side of your orb into the double collect position, placing a special land each time.
Practice efficiency when low on cards. Save Choking Sands and Last Nightmare for the bigger creatures instead of removing a lesser creature just because you can. Some enemy decks will have few Choking targets so take the opportunity when you can otherwise it will become a dead card for you.
Mono Green is the worst matchup but thankfully it is not common. Everything else can be beat regularly.
This is a frustrating deck to play against. Sorry.
