Evilswarm is VERY easy it's just level 4 XYZ and some floodgates.
Just go first, summon Ophion, set your traps and be happy.
I am not using solemn traps because i wanted to test Crackdown.
Today i was wanting to make a deck focused on Utopic Future (Outside Utopia archetype) , but i still need to search more... Anyways Utopic Future works just fine here but you can exchange it for other XYZ or even a Verte Anaconda engine.
Any suggestions are welcome.
