@so you think is better if I put the efffects(reverb) on the master track instead of putting one audio effect in each instrument track?
No, don't do that either. You don't want the entire song to swim in reverb.
But also, unless you have a good reason, don't put the reverb on the track itself. That muddies it and makes it sound less distinct. No reverb makes an instrument sound like it has no environment, reverb on the instrument itself makes it sound far away in a big room, and reverb on a send from the instrument makes it sound close in a big room. This last one is preferred.
If I were you, I would send all the individual drum tracks to a stereo bus instead of the master. Call that bus "Drums", and have it output to the master.
Then create a second stereo bus and call it "Drum Reverb" or whatever you like. Create a 0dB send from your drum bus to the drum reverb bus. Add a reverb plugin to the drum reverb bus, make it 100% wet, and adjust the volume fader for the drum reverb bus to where it sounds good.
This way, the drums always sound full volume and clear in your mix, and you separately have reverb to make them sound like they are in the same space. Having the same reverb plugin affecting all of the drums makes them sound together, and it also saves on processing power. Win-win.
You can get fancy from there. I often create a stereo bus for longer reverb and a stereo bus for shorter reverb, then send to each as I like. I like my reverbs to be full of mid frequencies, so I usually cut the highs and the lows. If you compress the drum bus, that can glue the drums together (if done right) and make them sound more cohesive. And putting a compressor on the reverb bus can bring out the reverb sound a little too. And, lastly, sometimes snare drums sound better with their own reverb in addition to the other reverbs. A gate can be used to control the sound of the snare-only reverb bus.
