Hey. I have been playing yu gi oh with a couple of my friends for a little while now, and I keep running into problems with one of my friends decks, (2 of his own decks technically). I was hoping someone can lend me a hand to help me customize my deck, not solely for the purpose of countering his decks, but for being able to deal with his cards that would help my deckin various occasions as well. I run elemental hero, here is the deck list:

The decks my friend is using is: an Agent Deck and a Gem Knight Deck

I'll focus on the Agent deck as it's his main deck these are the cards I know he has)

Monsters:

3xMaster Hyperion

1x Agent mystery of the earth

3x Agent of Miracles

1x Archlord Kritya

1x Marshmallon

1x Honest

2-3xHecatrice

1-2xTethys, Goddess of Light

Spell Cards:

3x Sanctuary of the Sky

3x Valhalla hall of the fallen

2-3x Solidarity

1xHeavy Storm

1xMonster Reborn

Trap Cards:

3x Divine Punishment

1xMirror Force

he has a few more monsters that i cant remember as well as a few more magic and trap cards. The ones I seem to have a problem with is Master Hyperion, as he is incredibly easy to summon and destroys my trap cards when he is summoned and is a 2700 beat stick, with valhalla hall of the fallen he can easily summon monster with a fair higher attack then mine and when he has Solidarity on the field very few of my monsters can kill his, his Divine Punishment stops a majority of my magic and trap cards and fusion monster effects. With those cards I never seem to be able to keep even neos alius on the field for more then a turn as he can easily kill it by using Solidarity, a Master Hyperion or valhalla hall of the fallen and summoning something stronger then a 4 star.

His second deck, Gem-knight and gem knight fusion are kind of annoying, It's also rly good at summoning strong monsters in a turn, such as using gem knight alexandrite to special a beat stick from his deck and poly it the next turn. He only uses gem knight fusion for fusions, that and Future Fusion, however he can use his card effects from his hand to special summon several monsters the the field at once and recycles gem-knight fusion all the time to usually get a 2900 out which is tricky to stop when he has several cards increasing his attack and lowering urs, United We Stand and a card which reduces you atk damage by as many stars your monster has.

Usually the only way for me to beat him, (in both of his decks, mainly the agent deck) is to try to wipe his field of monsters then attack directly b/c he out damages me and when I am able to summon The Shining or my other strong fusion monsters he saves his magic and trap cards to kill them and then special summon a load of monsters the next turn.

Please help me find cards that work well with my deck and counter his cards. Thank you.
