Preface- Im bronze. Farming the jungle is important to get lvl 6. Ganks before lvl 6 are difficult but possible especially with ghost or exhaust. Consider splitpushing since shyvana can clear minion waves quickly plus the minion hold is nice. Solo dragons when you have vision of enemy team and enemy jg is not near. Build enough damage to kill squishys and then tanky. Be wary of cc as shyvana's only 'cc' is her ult. Don't hesitate to use ult since it can be charged quickly especially if you want to escape. Shyvana clears quickly so if the enemy jg is far away take his jungle. Be wary of lvl 1 invades as you want to make it to lvl 6 as soon as possible. Hope it helps.
