Level: -
Just work on getting your wizard level up, and get talents in this order. Attack speed > luck > crit chance > item chance + item quality > more waves > anything you want.
also, check the forum regularly.
i think MRDRR can help with beating the first level.
you get relics from doing daily quests, hidden achievements ( watch the credits till the end ;) )
and just play for a bit and you should get it. it took me about 3 months to realize how the game worked
yes as Hydraling said it's all about perseverance, if i remember correctly it took me quite a few tries and wizard lvls just to beat the 200wave game, first lvl as fast you can its all that matters, IMO the skills important in order are: 15%speed, 10%damage, 7%critchance, 10%luck, 10%itemchance, 10%itemquality, ofc when possible the wavemaster skill (500waves) is great, after that it dont matter too much as i have noticed =) and myself i love the littlefinger hero if you can get your hands on him,
i have had a lot of help in the beginning by both trying various tactics and tower placements and reading many of the forum topics, even though i think these 2 are the ones you should read last as they are for more advanced gameplays, it's also these i have found the most helpful:

https://mazebert.com/forums/topic/early-game-placement/
the top scores forums (longest survival, best max hit) also have some useful info and pointers on how others use their towerplacement with both some text and some pictures:

https://mazebert.com/forums/topic/my-highest-max-hit/
some a little old and outdated by the newer patches but still have some useful tips and info and probably many great things for a new player:

https://mazebert.com/forums/topic/general-placement-strategy/
https://mazebert.com/forums/topic/some-tips-for-new-players/
there are other useful info in other forums but i just made a quick check to fint the ones i remembered helped me, look around and you'll find tons of knowledge to make you a mazebertpro
also feed the potions to only 1 tower(your main carry) and mr.iron is THE ultimate support tower place him in 1 range of your main feed him speed,exp,key of wisdom, auraitems(speed,dmg,crit etc) and if you want to make him a dmg tower then also feed him all dmg items that you dont use(don't eat paintings) when he has fast attackspeed about 0.2sec or faster put 2 items from the withered set on him and he will push back strong bosses with timewarp that would have otherwise leaked, holgar is a very storng beginners carry(don't drink the mead though but swap it =)) well thats the basics the more advanced ones is in the forumlinks and on other forums i missed to link
i still have lots to learn myself and still haven't found a tactic that i feel i can't improve more i'm still working on the perfect set-up(if there is one^^)
oh btw the golden cards are only for the golden grounds map, as you can get all cards in the other maps as you play it is not needed to have them except for the legendary ones... but even so if you have them in gold they still show in gold on the other maps so you've probably already used some golden cards =)
hope that was helpful and gl hf
