I still use fusion actually.
In fact, I am thinking of a way to work this guy into my HERO deck.
There are two new types for the extra deck since fusion.
Synchro: A synchro monster is an extra deck monster that requires 1 tuner monster (like an effect monster but it says tuner on it) and 1 non-tuner monster who with the tuner have stars equal exactly the same as the synchro you are trying to summon. Say, you have Junk Synchron 3-stars, and man-eater bug which has 2 stars. 2+3 equals 5 so you can synchro summon for any level 5 monster that doesn't specify a particular type. (Zombie synchros needs plague spreader zombie (a tuner) and spellcaster synchros typically need a spell caster instead of man-eater bug).
The used monsters go to the graveyard.
(This guy got cut off, I know)
Then there are XYZ.
Now I don't personally have any XYZ but I can explain this more or less.
XYZ: Say, this time you have that man-eater bug on the field, and you summon junk synchron activating its ability to get another level 2 on the field.
You can then XYZ summon a rank 2 (yes rank, they don't refer to it as star to get past level limit area b and other star-based cards) XYZ monster from the extra deck if it requires 2 level 2 monsters.
The kicker with XYZ is that the monsters used to get it out are then placed under the xyz to be used as "xyz material". It will explain their use in its effect but when the material is used, it is sent to the graveyard so that man eater bug can be revived after use if you're crazy enough to attack with man-eater bug.

Utopia as shown below needs 2 level 4 monsters.
It is important to also note, these guys do not need a fusion card (Synchros need tuners, XYZ only need the listed monsters). They only need their monsters.
