You'd want to post this under the casual decks section. Secondly, use to card tag [(deck)] [(/deck)] around the list with no commas, without the extra parenthesis ( ).
To get to your deck, most of your cards have absolutely no synergy with each other. Pick what you prefer (aggro/midrange/control/combo) and it'll be easier to recommend what cards to use.
i play mostly with creatures with high defence and spells that counter actions. and after i secured i am not gonna die i attack with creatures and spells... so... maybe not aggro... thats my best guess...
Honestly that's not a good strategy. The way you want to play the game sounds like you want to play control, but control tends to sit back and kill and counter your opponent's threats until the late game where you unleash your win con. Playing high defense creatures just for defense is bad since they can get killed easily and doesn't solve the actual problem of your opponent's creatures. It's better just to play removal.
To sum it up, play a bunch of blue bounce spells and red burn spells for removal (stuff like Lightning Bolt, Lava Coil, Blink of an Eye, etc). Play counters for things that you know that will be hard to remove (ex: Counterspell, Negate, etc). Finish them off with something like Niv-Mizzet, Parun and Aetherling (which is practically guaranteed to never die once it hits to field as long as you have one land untapped since you can blink it with its own effect to dodge any removal and swing for 9 unblockable every turn).
thank you :')
