Ok bro you should put some blue eyes summoner and remove your other dragon monster... you shoud also try to remove the spell and put some defence like windstorm or mirror wall or something that will help you stall your enemy... dont forget that wyvern is a card with a great effect BUT you should also remember that you can NOT summon a monster so that the effect is activated... Just try it.
Literally the only rare card from a pack is Red-Eyes Wyvern and that can do fine even if you only have 2, so just reset the box as soon as you pull one and open until you pull another one. The rest are farmable or card trader cards.
