Usually what i try to do is summon the Rank 11
Superdreadnought Rail Cannon Juggernaut Liebe with its effect after summoning
Superdreadnought Rail Cannon Gustav Max and dealing 2000 points of damage for free(your way of summoning Gustav is with the
Heavy Freight Train Derricrane and
Flying Pegasus Railroad Stampede or 2 Freight Trains). A perfect hand will lead to a perfect game, almost no way to beat you: you Will have a 6000/6000 Monster that(because of
Infinitrack Goliath) cannot be destroyed by card effects and a
Cyber Dragon Infinity to block any major effects that would target your monsters.
If you have 3 xyz monsters and no way to use their effects(no materials left), you should summon the big link monster with those 3 and start cleaning his board with both his effect and the effects of monsters you re-summon.
This is about it. You will learn the rest as you play
